Am I an idiot or is he?

He does care about health and safety, really!



I've been following this guy for a while now, despite all he does, he's not dead yet

But what he does as a job is different than what he does as a hobby. He knows what he is doing when he works with electricity... he doesn't know anything when it comes to lasers, despite him thinking otherwise.

Things said:

Sure, for the noobs that don't have a clue what the deal with "grounding" is.

However, while touching the live, IF he had touched ground, he might be dead. He didn't, though.

While "shaving," IF he had put his eyeballs in the beam, he might have a minor blind spot. He didn't, though.

I think usually he flips the screen on his video camera around so he can see where the beam was going.

A few words from a new vid

"Photonicinduction's not gonna blow himself up... It's not because I'm cocky, it's because I'm competent."

"and as for lasers and things, well, much experience on that... it's normal respect, y'know? You're not going to get a kitchen knife and stick that in your eye. You've got to treat a laser with the same respect as a kitchen knife... It's common sense. Health and safety is implemented, but at the right place and at the right time... in creating some of these videos, what I do - hopefully - is entertaining and interesting. But it doesn't mean you've got to try it"

"don't copy what I do; just enjoy the videos, and don't panic - especially with lasers. Lasers are another subject. 1W is trivial, but it needs respect - the same as a kitchen knife does."

I would MUCH rather be in the same room as a photon lexicon veteran with a 40W green... than a laser community newb with a 1W pointer.

Hey yeah saw that....

We have been chatting back and forth for a while now...

This is the email I send him when the video came out...

Hey Photonicinduction,

I really like to thank you for taking a responsible stance in terms of laser use. To be honest I am worried about the laser hobby. If we have people as influential as you pointing lasers near their eyes, this could potentially give others ideas about doing the same thing. Other people are not as competent as you or I in the field of lasers and could quite easily hurt them selves.

The laser hobby has been given such a bad name lately because of incompetent individuals hurting them selves or others and I am trying to do my best to stop the snowball effect and educate people in safety. I am, like your self trying to increase the popularity of the laser hobby but at the same time would like the participants at the end of the day to be safe and respectful of the power they hold.

and he responded...

Hello mate,

Cheers for the kind email, I know what you are saying, guns and knives have a bad name here because of a few idiots.

I will do a bit more with the lasers and advise accordingly for those who are unaware,
Surely though, you don't use goggles yourself for 1w when it is just you in the room ?

With the visable wavelengths, I really don't bother, but with the 35w CW 808nm, and YAG pulses I certainly do.

Kindest regars to you mate

To which I replied...

Well wheres the fun in lasers if you can't see the beam

It's true I do not wear them at all times, but while setting up or aligning the beam I do wear the goggles. But on the other hand, I never point anything at my face. So it just depends on the situation.

I really appreciate you taking the time to give others a bit of info on laser safety. It really does go along way.

Which he finally responded....

Hello mate,

Yes, I do agree, on setting up I have the power right down just so beams are not going all over the place, even on the vid where it was in the face in a line, it was at 300mw and not 1000mw.

As the screen name suggests Photons and Induction are my speciallity, although I don't do much with lasers now, Argon Ion and Yag were my interest, but the DPSS is much simpler to operate.

Somewhere in one of the vids is a picture of a large fram Argon Ion laser, water cooled and required 45KW just to output 13w at 488nm, how efficient was that

I will do a vid soon showing a 1w laser burning through some laser goggles and how the goggles can give you a false sense of safety.

Kind regards, al the best to ya

What's he plan on doing, focusing a 1W laser 6 inches away from a pair of goggles?

Just to educate bobhaha a bit more before he posts things about people he does not know. For everyone else.. Please continue to have much fun and enjoyment from lasers !

I believe you mean "light amplification by stimulated emission of radiation," my friend.

Based on that, what conclusions do you think I should be drawing concerning your expertise?

-Trevor

Just for bobhaha, the laser was only operating at 300mw, calculating the beam power in a fixed line the output in the retina area if the laser were to come into contact with the eye would be 1mw or 2 mw.
There is a nice link at the bottom of the thread so you can see all you said is incorrect, I am offended by your actions posting things on the internet on people do not know or understand, my company in the past has built lasers that you could only have wet dreams about !
You would be well advised not to assume I know nothing on lasers, and certainly not an idiot !

Watch this if you have any doubts about Photonicinduction's skill and knowledge:

I think he's great fun. :beer:

Yes, words, spelling and books are not my speciality, pratical hands on projects and experiments that get results are however.
Thank you for your quick reply.

I don't need education on anything. Those lasers used in the laser show have mapping software that allows the brightness level of the laser to be reduced when ever the beam comes within 2m of the crowd level. The laser its self would be capable of multi-watts of power, but it would never be allowed to scan the crowd at that power.

Events have a MPE rating for when ever the beam will scan the audience. The MPE or maximum potential exposure rating, differs from country to country but is never above 5-10mW MAX.

Just for clarification, I never called you an idiot.... check the thread. I have no doubt you are well advised in the electronics industry, but frankly there are members here with much more experience than you and they have even posted that in their eyes this was idiotic.

I have subscribed from pretty much day one of your videos and have seen every single one. Never did I pull you up on the dangers of the electrical work you did because, as unsafe as it is the potential for damage to your self is minimal. This on the other hand 1 struck a chord with me because, as we spoke about, I take laser safety seriously and 2 because the potential for risk was quite high.

Also if you read the thread you can see the thoughts of you shift with your comments. I was giving people the freedom to express their thoughts about you (which they did), then with every new comment they started to defend you.

Like I said in our private messages... The laser hobby has been given such a bad name lately because of incompetent individuals hurting them selves or others and I am trying to do my best to stop the snowball effect and educate people in safety. I am, like your self trying to increase the popularity of the laser hobby but at the same time would like the participants at the end of the day to be safe and respectful of the power they hold.

Only if the operator knows what he's doing. Many of them don't, especially in Europe where the laser laws are far more lax.

It's permissible, and it's measured in power density, not power. A 100mW 1mm beam is more dangerous than a 1W 30mm beam.

I think it's 10mW/cm², and there are many areas in Europe that allow shows at 10xMPE (ILDA is/has considered raising the limit to 10xMPE). Furthermore, many shows have been done at 100xMPE with no reported injuries.

Thought that sounded wrong, cheers.

As for the MPE rating... it depends on wavelength. In Australia if the wavelength is less than 500nm (IIRC) than the MPE is calculated by the exposure time otherwise it is calculated by the output of the laser + divergence + other factors eg time for scanner to decelerate etc..

It's also calculated in J.m^-2. As you mentioned, in Australia the limit is 1W/m^2 which is 10mW/cm^2

looking at all his other videos , it seems he has a good grasp of potential harm from his experiments.

on another note , the "oh my god are you wearing safety goggles" or the over protective you should be banned because you dont have the necessary goggles. thread has been done. he did not post his link here to affect prospective users of lasers from the beginning until you alerted users of this video

lets chill out on trying to get the world to wear goggles. if you are playing with lasers, wear the goggles... period. but lets not make it a do it or you die ,cult.
