spectra physics fiber coulped laser diode type 0129-2653 Rev

[The_Praiodanish]

Hi there,
I've got a spectra physics 0129-2653 Rev. D laser diode a few days ago
but I don't have any specs about the operating current / threshold
current; I only know the wavelength is 808nm and Pout is about 30
watts.
Does any one have more detailed information on this diode?

Thanks, Thomas

Typically, a 30 W diode will have a threshold of 8-12 amps with
30 W at 35-50 A depending on slope efficiency. The only way to know
exactly without measuring it (assuming the diode is good) would be to
get the original test sheet from Spectra-Physics.

That's only rated for 12-13W from the fiber. The diode inside is a 20W
unit. Max current should be 25-27A.

Hi there,

thanks a lot for your information. I expected the diode to be the 40W
model but 20 W should be ok for now...
