Bibliography:As one of the key components of high-pow er optically pumped THz laser,hybrid metal-mesh output coupler is critical for the output pow er and the beam quality. A model for the hybrid metal-mesh output coupler has been developed. The reflectance,transmittance and loss of the coupler w as evaluated. Output couplers at 2. 52 THz have been fabricated. The reflectance and transmittance are 70% and 11% for type I,87% and 4% for type Ⅱ. The coupler can sustain high-pow er CO2 laser pump w ith the reflectivity over 95 %. This research provides theoretical and technical supports for developing high-pow er optically pumped THz laser.
