New diode Mitsubishi : ML501P73 638nm 500mw

[nain-nain]

Hello

We already know the diode Mitsubishi ML520G72 but there is a new one :ML501P73.

The divergence is quite lower, may be it would be better than the ML520G72 ???

Diode is capable of 1W pulsed 1/3 duty cycle... here is a blog with some pics

the question is how broad is the emmiter on this broad-emitter diode....

If it looks like a duck, walks like a duck, if it quacks like a duck, its a duck. Trust me, odds are it is still a video projector driver diode, designed for driving a optical integrator, not a collimator. I've had my hands on the 072, and while a NDA forbids me from sharing details, you are much better off with something else.

Hi Steve,
What diode would you recommend for building a quad red at around 2 watts, that could achieve a decent beam (say, no worse than a 445 quad) and not break the bank? (Brighter, shorter wavelenght reds are preferred)

Thanks!

i think ever single person in the laser world wants a cheap powerful decent beam red module, but guess what? this doesnt exist!

Well thanks for the reply....

AFAIK if die size is same and divergence is lower, the final beam specs will be worse.

2 years ago, you would have made the same quote, replace "red" with "blue", and there was no doubt about that.

If I told you back then we would have 1W of blue for under $99 in 2 years, everybody would call me 'Allen' and laugh at me.
