Popularity, technology advancements and price point are 3 major factors. Hand held lasers used to be $2600 verses $70 now and cheap ones are <$10

I just went and counted. I have 10 working. 4 in use.

Did some research. It is a juvenile Redtail hawk. Hence the red color has not developed in its tail yet.

Welcome back :wave:

^^ Busted out laughing and knew in a split second what it meant on the 10th :D :D :D

Sure do know AC/DC = great band IMHO

I am not sure but Redtail hawks are very common in this area. Here is a picture of it once it settled down after it flew back.

Hi Wooski :wave: Welcome to the forum. Warm after 15 seconds and hot after 30 seconds should not be happening. That is way too soon really unless it is a very high powered diode and little to no heatsink. Check and see if there is not a short happening somewhere. That would explain both the...

So true, most (not all) of it is just media and airliner hype to force the hand of the government against lasers unfortunately.

^^ So sad for the innocent people on that plane!! :( :(

Hi Ed :wave: Welcome back, hope you are feeling better! :)

See ya ... hello again. Spotted a beauty in a tree. Just as I went to take a picture it flew off. Did about a 300 yard circle to check out a field and then came back to the same exact perch.

What is the project? What do you want to burn/cut? At what rate of travel/speed? Will it be going in a labby or mounted on a printer/cutter type machine? That alone will drastically change parameters.

It is a good topic to bring up. I have sold some of my lasers to research labs that needed it at +/- .5nm a certain WL. Of course some diodes can be driven to change their nm a bit so output should be stated at what it is outputting for the settings of that laser at that time.

I knew 4 times the power is ~ twice the brightness from years ago but I did not know if a PBS cube would affect that any. I guess not. Thanks for the confirmation :gj:

Just want to make sure that you know that 450nm is blue as you posted this in the green lasers area :p If you like to tinker then building is right up your alley. Sure you can buy an already built cheap laser but you get what you pay for most of the time. The ratio of already built to building...

The strongest 532nm I have personally seen is 1100mW and it is amazing. @ Ultron = The laser in the picture appears to be a labby or else Alaskan uses some serious heat sinks on his hand held lasers!! :D :D

The suns magnetic fields play the largest part because CMEs and solar flares typically erupt from what are known as the active regions on the suns where magnetic fields are much stronger on average.

I have seen you state that before so I did some poking around and you are right. It is not any easy WL to find. I have some lasers in 650mW and you do wonder if you should hang onto them or not. Good luck in your search for those elusive 650nm diodes!!

I agree. I have about 15 green 532nm lasers left and even though they have beautifully tight beams that appear to go on forever and can burn and be seen really well because of that. The 532nm lasers very nature does make them picky to temperatures above 95° and below 35° and you have to be...
