Stabilization of the emission wavelength of a neodymium laser by an interference-polarization filter

B. V. Kuznetsov


Abstract: The effectiveness of using a thermally compensated interference-polarization filter in stabiliziation of the emission wavelength was demonstrated for a neodymium laser whose resonator contained this filter. Variation of the ambient temperature from +20 to +40${}^\circ$C altered the emission wavelength by not more than 0.5 pm. A method was developed for designing a thermally compensated filter of this type. Measurements were made of the thennooptic coefficients of several crystals. The results were used to recommend pairs of crystals for thermally compensated filter stages.
