Tunable single-frequency calcium-hydrogen laser emitting at 5.54 μ

An investigation was made of a cw single-frequency Ca–H₂ laser. The dependence of the output intensity on the resonator length was determined. The energy characteristics of a laser tunable by the application of a longitudinal magnetic field were investigated. Measurements were made with the resonance line of the resonator tuned continuously to the central frequency of a Zeeman component shifted by the magnetic field. The rate of shift was 1.41±0.02 MHz/Oe.
