Multipass-prism interferometer for fine-frequency-tuning, single-mode operation of TEA CO(2) lasers.
A novel interferometric configuration has been used as an efficient, narrow-band output coupler for high-power lasers. Its application to a TEA CO(2) laser has resulted in extremely reliable (100%) single transverse- and longitudinal-mode operation of this laser with a fine-frequency tunability of up to 3 GHz.
