Default Re: 50w Osram 450nm diode module!

Quote:
The result is an extremely powerful laser module which can be more easily integrated in projectors. Its package measures 25.5 by 35 millimeters (mm) and accommodates four copper bars with up to five blue laser chips connected in series and operated at 2.3 A each. This multi-chip product offers a light output of 50 W from a typical electrical input of 165 W
A boost driver is going to be necessary. And you'd definitely need a beefy driver and battery to supply 165W of total input power. Then comes the part that we usually overdrive the diodes.

Default Re: 50w Osram 450nm diode module!

SOoooo many questions !! Drivers will be made...Power MAY be somewhat more problematic !! Cost may be somewhat steep... BUT....the BIG question is....CAN THE COMBINED OUTPUT BE COLLIMATED AND TELESCOPED DOWN INTO A SINGLE AND REASONABLY SIZED BEAM GEOMETRY WITH ACCEPTABLE DIVERGENCE ???

Remember....THIS is made for a RGB projector....a very different application....After further thinking....I have serious doubts that this unit will fit our purpose !!! BUT likely....will be a single light source for an RGB projector.....and in that application....very possibly cost effect in replacing ALL the other sources now employed !!

OH....One could have 20 emitters....FAC'ed.....THAT WOULD BE CHEAP !!!!
HAHAHAHAHAHA !!! And then...the individual propagation alignment would be akin to the eyeballs on Marty Feldman !!! ...NO...this is likely a dead end !!! Hope I am wrong.....we will see !!!

Madmacmo linked to this in his technology thread. And I woildnt be surprised if nichia switches to the same platform, im 100% sure they hate that we have access to their diodes.

Default Re: 50w Osram 450nm diode module!

Yeah, plus lower cost and simpler design for the projector manufacturers ++lower cost diode modules
= lower cost projectors = more sales. They're banking on a snowball effect.

Default Re: 50w Osram 450nm diode module!

They can try all they want, we'll still find a way. Ain't much longer and we'll have a DIY way of bonding gold wires to bare chips. Heck, there's been a page up for about a decade now, showing step by step how to solder a bare laser diode resonator using soldering iron, hot plate, flux, and some eutectic solder. This may make it harder for us, but it won't stop us. Heck, might even be feasible to just cut 'em out and attach wires. Mounting them may be harder without a standardized package, but with everybody's collective knowledge, we can find a way.

We all tout Nichia as being industry leading. On the surface, they don't want to be associated with us. But, in their heart, they lurrvvee us!

Default Re: 50w Osram 450nm diode module!

In time they will be single emitters, possibly RGB for better image quality, but just 1 of each.
It's a matter of what is most useful and yields the highest quality product/images and is most cost effective.
Hell there may be just one big diode with a RGB in it.
