PHASER diodes! HELL YAA!!

Cant wait to get one .

Alright... The results are yet to be graphed then... but... I pushed one of the diodes up to 700mA and achieved a maximum of 323mW (TEC COOLED) from one before it just gave up and turned into a VERY expensive LED...

700 mA.. its amazing it took that really. Given proper cooling i guess these could be operated at 350 mA/200mW for quite some time, and with decent overhead too. Not a bad result at all!

I'm i reading the earlier post right that the beam is visible can some one explain why some reds are and some not.

It's a matter of wavelength and power really. The beam from these 150 mW+ diodes is visible to some extent, even though their wavelength of 650-660 nm doesnt appear bright to the eye. In fact, the beam from a 30 mW green is probably more visible, also because shorter wavelengths also scatter more easily.

It's a bit of a hazard really - the beam doesnt even appear to be insanely bright, while at these power levels it ingites matches in a split second when collimated.

You got that right! ;D I swear I have the videos on my camera... just need to get them on here... I'll do it soon... I promise... :-[

Glad to see you're doing some good testing. What is the model number of these, and is there a spec sheet?
k thx.

 

[Daedal]

Hey there DrLava;

There is no model number, and there is not spec sheet... ;D

Hence the testing

These units are not commercially available, and thus fall under the same category as what MaxYZ uses for their lasers...

wow i just read this thread, you really have your hands full Daedal! these diodes look VERY nice, are they robust though? i mean they arent like an open can, powerful but weak at the same time are they?

well, i suppose since you havent actually broken one yet you wouldnt know how resilient they are

so, would a GB kryton barrel be good heatsink ing for one of these at 400, or even 420 ma? what is the max you suggest to push these things (ma wise) in a kryton barrel?
