Hello all,
Can anyone speak to the feasibility/difficulty of retrofitting DPSS lasers with more powerful pump diodes?
It has been a while since I made a hologram, for several reasons including the mediocrity of my laser (50mW 532nm) and hassle/difficulty of cleaning glass and coating plates.
These are problems that money can solve, but we try to keep the wallet happy too
There are plenty of relatively cheap JDSU uGreen and C315-20 lasers on eBay, and I was wondering if one could replace the pump diode with a much more powerful one. What would prevent one from replacing an 808nm pump diode with one which is twice or thrice as powerful? Assuming you select a high quality 808nm diode, of course.
Unless the higher power would damage the optics or something, the only impediment I can think of is the controller not being tuned right for that diode. However, the C315 controller can drive many different laser heads of different power outputs, so assume one replaces the pump diode for a hypothetical 75mW C315 laser head with one which is twice as powerful. The C315 controller can drive a 150mW laser head just fine, so what am I missing?
Any info would be appreciated.
Thanks!
