Abstract
For most applications of Far Infrared (FIR) lasers, sufficient output power on as many lines as possible is as important as good beam quality. In order to provide optimum coupling to the EH11 intracavity mode and thus to achieve optimum power and a Gaussian beam profile, hybrid metal mesh couplers are prefered over most other coupling techniques, since no aperture diffraction occurs. Application of our mesh-couplers to FIR lasers yields output powers of tens of milliwatts on many lines, even when pumped with moderate powers in the 10-60 Watt range. Gaussian beam profiles with low divergence angles were achieved in all cases.
