Steve's 6-7 watt 110V green medical yag
=========== 2 KW xenon pump lamp
( Q ======= I ! LBO ) -----------532--------
HR Q yag iris IM LBO OC
Q = qswitch. I = SMALL IRIS ! = intermediate mirror.
The YAG rod lases at 1064 between the HR and the Intermediate Mirror , with a AO qswitch at Q.
A iris limits the mode and controls beam diameter. The LBO sets at the TEM beam waist from the IR cavity, the HR reflects IR back at the LBO causing a overlapping second waist creating more power but passes green. A opposite curve built into the HR collimates the green. The LBO is angle tuned about a axis looking into the monitor by a computer but is not in a oven. CW power is about 500-700 mW at full lamp current, 6-7 watts Q switched at full lamp in service mode. Designed to deliver 2-3 watts all day via a very small fiber. No V fold either. Some have simple spinning disk q switches instead of AO.
beam comes out very small and collimated.
mine has a dead lamp power supply, but I'm working on that. No expensive pump diode, and lamps are about 150$ each and rated at 400-600 hours. Design is patented by the French.
12-20 nS pulses at 24 khz. qswitch is not great for graphics unless you know the trick Patrick Murphy came up with, change the speed of each sucessive frame a few %. Ie 29.5K 30K 29.5K 30K Fills in the dashes :-) I've ran graphics off a CVL before this way.
My medical buddy has a pile of them working in his barn, but wants 5-6K$ a piece. most of them out there are 220 single phase,and are the rough size of a two drawer standard filing cabinet. Cooling is a water to air closed loop system, external water is a option.
Questions? :-)
