-The smoke was just a little fog from the machine -Yes they are the lasers in my sig...all of which i've received within the last few months -Yeah I noticed that right away....I think its just the beam reflecting off of the hardware on the door....No worries though I was wearing my goggles :)...

Thanks..Yeah they didn't hold up too well :) I tried to make quick work of it

Just doing some experimenting :) 450 and 405 no fog 445 450 445 no fog 532 and 520 some fog 450 445 405 445 520

Wow that rocket was impressive! Haha

I first bought a sword a few years ago because I was always fascinated with them as well. After receiving it I inquired about whether there was a place locally that I could train in its use. To my suprise I found a gentleman who is a sixth degree swordmaster who trained for years under a 9th...

I train several times a week in Toyama Ryu Battodo (strictly swordmanship). However, I don't get out to much lately to do any cutting due to being in the middle of the school year. No it is not damascus. This sword is just a low range competition cutter from Hanwei. They cost around $200...

Here's something else I like to do with my spare time I hope you guys enjoy it! :)

That's right, it can't be determined by pictures. However, there is clearly fog or smoke in the second picture enhancing the beam.

"To be or not to be" that is not the question...that is the answer The question is: What is √(4b^2)?

Great. Thank you Pi. I didn't want to take any chances due to the sensitive nature of the diode :)

I don't like the splash either. Can I use the 3 element that came with my sci-fi 445nm in my 900mW 405nm laser? Or will it damage the diode overtime due to reflections? Sorry for asking in this thread but can't seem to find an answer to this

My quick and cheesy attempt at a rainbow. From left to right 650nm ---?mW 520nm---200mW 450nm---100mW 405nm---900Mw I guess I have to resize the picture before I put it on FB next time. My apology for the size.

Not sure if you are still looking for an answer, but the reflection depends partly on the angle with which the light it hits the water. I can't remember if it is affected by wavelength. There is a critical angle where all or most of the light is reflected. Similar to the critical angle which...

The range of the fluctuation on the 532 is around 150mW (i am assuming this is a 500mW laser). I understand that 532's do fluctuate more, but is it normally that much of a percentage of the total power?

I've been looking for something similar. I found this, which doesn't look too glossy, and is reasonable as far as price goes: Tillman Welding Blanket - Thermofelt 615

Purchased the 405nm. Arrived in 3 days which was extremely fast considering that I bought it on New Year's eve. This is a nice little laser. Well worth the money imo. Thank you!

Thanks. I wasn't aware of that launch schedule. I will certainly look. We can see all of the launches from here, provided the skies are clear.

I'm going to go look outside to see if I can get some pictures when they shine it again. I am near Orlando. Last time I tried the night before the launch, but it was cloudy.

I second that. I bought two lasers from Eitan within the past couple of months. He was there to answer any questions I had, and always with a quick response. I will definitely be buying from him again. There will always be people out there like that. No need to let to let them get to you, as...
