Hey Max -
Well, without getting too technical, it is SIMILAR to a PCAOM, in that it is an RF-oscillated crystal, that 'passes' laser lines like a 'gate' - in this case,
both the 1064nm IR and the 532nm 'green' - but
unlike a PCAOM, it acts more like a 'light paddle', than just a 'gate / wavelength selector'...
As I understand it,
(and those of you experts out there please correct as needed) with the coatings that are on the Q-sw crystal, like a PCAOM, when it is at one 'angle', it simply passes the 532 thru, but when ACTIVATED
(and to answer your specific question about 'enabling' - that is a reference to putting 'power' to the Q-Sw RF-DRIVER - typically, +24VDC), the driver sends its RF TO the Q-Sw, 'oscillating' the crystal - but UNlike a PCAOM
(which just passes/selects wavelengths based on that RF-controlled 'angle'), the 'Q' acts like a 'light paddle', where the coating for 532 'reflects' it back INTO/THRU the KTP crystal, thereby effectively 'doubling' the amount of 532 produced
(efficiency depending on several factors, like KTP crystal-temp, alignment, etc) - Then as lamp current is increased, you will get more IR from the Rod, producing MORE 532, which then gets ~doubled
(again, based on those 'efficiency factors) by the Q-Sw, and you've got 30, 40, 50, 60 or more Watts of 532 - it's
quite the design...
- Did I get it right, Pro's out there? ie: Laserman532 IS a KTP Experts' Expert.
(he more or less designed the first show systems EVER, used to WORK FOR Laserscope...) his system work is
phenominal - makes mine look like a lego-laser!
Make sense? I'll see if I can dig up some print on it and post... peace..
