Hi,
i got a Lasever LSR473ML-100, and I'm surprised how much current it draws (with the Lasever PS1): 4.5 Amps after the TEC starts running. Is this normal?
Would be very grateful if somebody knows...
Best,
Michael

Im not sure but from what I know is that blue dpss (473nm) are not efficient from its lower gain material (BBO or LBO ) tends to have a efficiency of 3-5%
So I think its normal that it draw over 4Amps for a 100mW output, I could be wrong :P

I guess a lot of the current might be from the TEC. Not sure if the if the diode draws so much. But it could be...
The output is correct at 100 mW. What do you mean by a lot of current? Would 4 Amps be unreasonable?
Another contribution to low output or dead is with some 473nm dpss using BBO or LBO which are know to be hygroscopic which attract moisture therefore degrading the crystal,
not sure but a better substitute would be BiBO, dont know which manufacture use which crystal
