CrystaLaser diode swap

[gogu]

Hello everyone,
i'm new here and hope my q don't sound dumb, but there seems to be a lot of knowledge here when it comes to lasers
I have some crystalasers GCL-015/25-L and was wondering if anyone can identify the diode in the laser. I would like to swap it out to something that has more power. I measured the diode to be about 350mW (could be 500mW i couldn't bring the lpm head close enough to the diode without disconnecting it completely) and i'm getting about 50mW of green out.

this is the inside of the laser:




this is a closeup of the diode



would i be able to swap it out with something bigger, and where would i be able to find a replacement.

That diode is not a standard package and you probably can't get a replacement unless you make it yourself.

Hi!
It is still a standard package, but not as often avaiable as C-Mount.
This Diode is called CT-Mount package.

maybe a new copper block with a C-mount upside down?

I think Kevin @ Junktronix has these from time to time (member here) or Stan Tureki also sells them on Ebay. The second option may be subject to controversy as he has a name for being an unreliable seller. That said I have had nothing but good comms and deals with him - albeit about 4 years ago.

Best way to gauge the power if you cant measure it - and if its fooked then the reading will not be any use anyway - will be to measure the didoe current. This should not change if the diode has failed and will give you an idea of the power - match current to nearest higher specd device. ie if you measure 1A and you can buy one that maxes out at 1.2A thats your boy!

nice beam shaping arrangement!

Hey guys, thank you for all the replys
I put a meter on it, and i'm measuring about 200mA, the driver board has an adjustable pot that can be turned to put out about 350mA at about 1.5v. (i measured about 350mW with an lpm)
I don't know a whole lot about electronics unfortunately but i don't think i can upgrade it unless i modify the driver board to put out 1 to 1.2A. Do you guys think that would even be doable?

Thank you,

Most often the way to increase the current would be to change the ballast resistor thats in series with the diode - this may be 0.5 ohms some are 0.33 and for higher currents 0.1 ohms or less. Its likely though that its not as simple as just that - you may also need to mod the volts supplied to the pot you have marked - it may be a lot of hassle if you are not electronically mined. Maybe you should look for a 500mW pump....
