Hey All

After Going around on ebay for lab lasers , i got lucky and scored a laser quantum Gem 532nm Laser System OEm Style :D

I won the system for 400 usd :p Advertised with 2000 Hours on the system but after finnaly getting it going as it can only be turnd on and off via the RS232 Port it turns out its hours are 1825 so 175 Less than advertsied :D .

using a terminal programe the cotrols are ON , OFF to turn laser on and off then after the ON command is issued then POWER=XXX can be used to set power where laser will regulate to that power . head/psu Temprature read , hours read , diode current in % , power in mW , calibration can all be read over the RS232 port .

The Unit aslo has a built in Power sensor to sence output :D and messured output at full is 505mW @ 88 % Diode current , After readings sams FAQ these modules can be tricked into outputing over rated power , some have done over 1 Watt CW for low milage systems

As the laser was made to be finber launched the output is 100Mrad or so i belive :p so i need to find a lense to correct the output into a nice beam .

Was soo happy the system works as these are expenive systems new made in the UK

Here are a few pics of the system with raw output , More pics and videos to follow :)

Sweet find! The price was right, that's for sure.. I used to have a Quantum Excel 1W, but it died young at around 2500 hours (and out of warranty since I bought it used) a year or so ago.. They are very good lasers though, especially for lab use. I'll not be using a cavity that complex for shows anymore though.. the added complication doesn't seem to do much for reliability under the demands of traveling show applications in my experience.

I just saw your latest pic.. what does the profile of the uncorrected, highly divergent beam look like?

Thanks :) , Shame it died ealry :( , Heh yeah i can guess complex cavitys do not like the motions of travel ... they prefer sitting in a lab making photons :D

Raw Output is a very nice solid green circule at any distance , its probably the lense im usning to correct the beam casuing the 2 beam output .

you should be able to collimate that quite well.

Looks like a pro laser for sure, shes a beaut. +2 on your find
