That host says the output is 350mA, not 1A like you said. Also how did you take "a couple of 350 chips off a Njang 1.4 A driver, so I could get approx 700 mA"?

yeah redcowboy is right, with the tremendous amount of fake news widespread you really can't believe any news agency outside of independent reporters like mark dice.

I got this quote from a banned member a few months ago about that n company. btw don't mention the name of the company in this thread, I put asterisks in to hide the identities of the diodes.

from the video it looked like somewhere close to 1000 feet of the ground but hard to tell because they were zooming in on the laser.

well to be fair, a pilot's eyes are his or her livelihood. If I were a pilot and someone shined a laser in my eyes I would take every precaution to ensure my eyes are healthy.

Be sure to show us some pics of you using it and maybe some burn vids!

Yeah I forgot to include an explanation about the DPSS green lasers and that is totally true. But for just single diode InGaN lasers the reason is still due to Debroglie's law since these InGaN blue and green diodes use the same semiconductor dopants.

It was DTR and he is so right. I was ripped off by wicked lasers who claimed they sent me a 350mW red laser about 8 years ago and it was a piece of crap. It took over three months to get here, it showed up with scratches on it, and it was severely underpowered. Also the button for it fell off...

in the words of a wise man on the forums here, "if you can't afford to get ripped-off a few times, this isn't the hobby for you"

energy is inversely proportional to wavelength. the higher the wavelength, the lower the energy

yeah you got ripped off man, go to your bank or paypal or whichever and get a refund. buy this one in 1000mW PL 405/445nm 500-2000mW or check out this site https://www.sanwulasers.org/ also read this thread when deciding on what company to buy from...

Re: What is the main cause of power drop off ? basically the diode gets hot. heat creates more resistance, therefore less current travels through the diode (i.e. V=IR)

where did you buy this from? it looks to me like you bought a cheapo ebay laser LOL sorry for your loss mate, id ask for a refund

Well yeah I just found out that there probably isn't even enough NUBM44s to make this happen anyway

I was thinking of saving up for a 1 kW laser rifle much like the one styropyro built in his video once I get my student loan paid off. What I would do differently would be to use NUBM44s focused independently with a G-2 lens', then much like styropyros to collimate them into one with a large...

You can get a pack of three on ebay; one red, one green, and one violet for a few dollars <$5. 5mw 3PCS Laser pointer Pen Red + Green + Blue/violet Laser Pointer Visible Beam | eBay If I was making Ph.D money Id be using this pointer for my lectures (the Aurora)Yellow Laser Pointers : Dragon...

Are you in the US? If so go to survivallaserusa.com they have a US site and a non US site, the non US site is just survivallaser.com

Well get some assorted wires and solders and start practicing on just soldering wires together to get started. The key to a good solder is when you apply the solder it effortlessly flows and surrounds the wires. (i.e. you dont want it to ball up) To do this make sure the wires are cleaned and...

Here's the do's and don'ts of cleaning a lens... Don'ts: -touch with bare hands -use Q-tips (cotton will end up on your lens) -use Kleenex (cotton will end up on your lens) -use paper towels (cotton will end up on your lens) -use <97% alcohol (that other 3-5% is usually oil and will end up...
