Continuous 250 mW gas discharge DCN laser at 195 μm

The laser cavity is a 5.4 cm diameter, 3.2 m long glass waveguide with plane reflectors against its ends. The DCN molecule exhibits four laser transitions in the continuous wave operation (λ 1 and λ' 1 close to 190 μm, λ 2 and λ' 2 close to 195 μm). By tuning the cavity simultaneously for...

Description
Summary:The laser cavity is a 5.4 cm diameter, 3.2 m long glass waveguide with plane reflectors against its ends. The DCN molecule exhibits four laser transitions in the continuous wave operation (λ 1 and λ' 1 close to 190 μm, λ 2 and λ' 2 close to 195 μm). By tuning the cavity simultaneously for λ 1 and λ' 2, or λ 2 and λ' 1 lasing action is enhanced. Maximum output power is then 400 mW, with 250 mW corresponding to a single wavelength.
