Q-Switched CO2 Laser Housing
FIG. 5 illustrates a schematic overview of a laser assembly 100, including a laser housing 102 containing a sealed-off, folded waveguide, electro-optically Q-switched CO2 laser head 400 and various electronics, optical, an electro-optical modulator and electro-mechanical switches. A multiple pass zig-zag folded waveguide is shown at 806 within the laser head 400 for illustration purposes. A three pass or more than five pass folded waveguide configuration could also be used in the hermetically sealed laser head 400. An output coupling mirror (OC) 406 and turning mirror (TM) 414 utilize a metal O-ring to maintain the hermetical seal as disclosed in U.S. patent application Ser. No. 09 / 612,733 entitled High Power Waveguide Laser, filed on Jul. 10, 2000 (which is incorporated herein by reference in its entirety) and in U.S. provisional Patent Application Ser. No. 60 / 041,092 entitled RF Excited Waveguide Laser filed on Mar. 14, 1997 (which is incorporated herei...
