New diode!!! Nubm47-a1

7w at 4.5a is as good, or a few hundred mw's better than the 44 Jordan tested. The 06 is 1w short of the 44 with a slight increase in divergence from what I've seen. If these can be safely ran at say 5.5-6w, May have something. I want one if any improvement over the 44, divergence or power, card in hand....lol
 





I've been saying a lot lately concerning the new standard of power.
3.5 years ago when I joined the big deal was a 1W blue Spartan (a laser which I still own). I really don't like how things have changed for the much worse. Obviously I need to clarify that statement.
I am specifically referring to how it no longer is any big deal to own a class 4 laser and in fact it seems the new standard for a new person is in the 2-3W range. I just cannot see how it is a good thing for someone new to this hobby to start out with such a dangerous unit. There's no learning curve anymore on how to handle it.
I remember how incredible it was when someone (it may have been Pi) discovered Fasttech was selling 50mW 532nm modules and we were all buying them like crazy. Something a 532nm will give you that other cheap wavelengths won't is an easy to see beam that is not only fascinating but a place to learn to respect what you are dealing with. You see the beam and learn that the dot is brighter than your eyes are comfortable dealing with so even though it's not great at burning you can be fascinated and respect how you handle it. Now it's 2-3W of fire stick that is cheap enough that they are handled carelessly because you can just buy another one.
I remember when this race car driver was going to purchase a powerful unit for his first laser and how dismissive he was over the safety aspect. He claimed that because he knew safety from racing cars that made him automatically equipped to handle a high powered laser. Because you know the rules and safety behind something doesn't mean you get a pass for something else and I called him out on it which just made him madder and DTR whom he bought the module from was regretting he got involved with the guy. You think it would have been a go on my part if I said I knew all about Laser safety so I automatically get a pass on race car safety?
My point is its great that we have a bunch of choices and some really high output ones but there is a price to pay for it and there are not enough members suggesting new members start off with something way less dangerous but are encouraging the high powered norm.

That being said, I sure hope this diode has 20x what it takes to be class 4 for those who are truly responsible enough to treat it with the respect it needs to be given;) It only takes a micro second for something to go wrong and I just don't want myself or any of us getting hurt. Doesn't matter how long you have worked with these, the danger is always there and the chance of something happening can increase exponentially if we get too comfortable with them.

Well said Pman. Even though I think high-powered diodes are awesome, it scares me that people with no idea what they're dealing with can get them in ready-to-go form with no issue at all.

We hear about people lasing aircraft, athletes, and drivers with cheap green lasers pretty frequently already. Now diodes well into the Class 4 region are getting easy to attain without any sort of technical knowledge or skill necessary. I hate to think what will happen to the obby if kids lase themselves to blindness or cause permanent damage to a pilot's vision.

I know it's been said a lot on the forum, but this sort of stuff definitely frustrates me since similar situations have affected my other hobbies (RC flying and marksmanship) to the point where I have diminished enjoyment.

Well, fortunately the 445, 520 and other direct diode lasers usually have pretty bad divergence. The increased eye hazard is somewhat offset by the fact that the spot will be a lot bigger when pointed at a plane, sports player etc. Now if somebody had a beam expander and wanted to harass people that would be very worrisome.

That's why we invite people in, not chase them away, and then teach them safety politely.

A single mode 1 watt 405nm is more dangerous at 100 feet than a 7 watt MM 450nm if both are using a simple screw in G2 or 3 element lens and new diodes are going to be highly divergent and that gives a safety buffer of distance to innocent bystanders, it's darn hard to get MM repurposed projector diode power to a burning point over a long distance, they are and will be highly divergent.

Yes safety is always needed and up close 3watts or 30 watts is dangerous but at 100 meters if Multi Mode they will spread out like a spotlight.

Safety is still very important, but there's no more need to panic today than yesterday.

These are not the doombringers.

I am SO PISSED OFF that they have ruined legal FPV flying. The ONLY way around this is to use a damn buddy box (trainer setup) to do true fpv legally. I was about to get into FPV planes and race quads.
 
They are doing special race courses where it will be allowed, god I hat that word, we free people will be allowed if we pay extra and go to a special place.

There will be big indoor courses, but I also am pissed, the FAA has violated their own prior ruling, there are lawsuits, but we need a hobby organization where we can pool funds and do something about it.
 
So I just did another run and these seem to be slightly stronger than the 44. I did about a 30 second run and it peaked just 7nder 8 watts and never droped below 7 watts. The crappy Chinese G2 I have has such a short FL that any tests with it would be pointless. I'll try it with another single element I have and see if that's any better.

And TrendKilla are planning on mounting a laser on a drone? I've wanted to do that myself. It would look cool at night.
 
That's a very bad idea and may be illegal, what if it goes rogue, it could hurt someone, just something to think about.
 
@ Trendkilla how has it been ruined? Here you just need a spotter and line of sight. I thought you just had to register, what's changed in the US?

PS good points Pman. I've seen kids pointing ebay 532s like they were toys, once whilst on holiday. They were actually aiming at people's faces, so I had a go at them and tried to say how dangerous it was. All they did was laugh and run off, I guess they thought it was funny. Imagine one of them with a 7 W, pointing at people at close range...Another issue is cheap sites, including Ebay, making these very high power lasers accessible to all.

My most powerful laser is actually an M140 at 2.5 W and to be honest I don't really need anything more than that. :thinking:

Edit: Mounting a laser on a drone is bloody stupid. One wrong movement with the sticks, a motor/ esc failure, loss of GPS signal if not in attitude mode, not to mention actually being able to predict precisely where the beam will go, could result in serious harm.

400 foot ceiling, line of sight only, not over any people, or within so far of an airport, it's basically grounded, the GPS and FPV has been ruined

Yep. Got my first quadcopter before the craze. Was just about to go FPV with my planes. When I flew I public before, people would be interested and ask questions. So many of my friends have been confronted (by "concerned" citizens) about flying in public recently that I don't even bother anymore. The public just sees RC in a totally different way now. Most of us still refuse to register.

Anyway, sorry to derail the thread a bit AB, let's focus on this awesome new diode again.
