The optical resonator provides optical feedback by reflecting light between mirrors, allowing photons to pass through the gain medium multiple times. This amplifies the light and sustains laser oscillation, determining the laser's output characteristics such as beam quality and wavelength.
Key parameters include resonator length, mirror reflectivity, output coupler transmission, optical aperture, surface flatness, surface roughness, thermal expansion coefficient, operating temperature, and weight. These affect performance, stability, and integration. Always verify these values with the manufacturer for your specific application.
Temperature changes can cause thermal expansion of the resonator materials, altering the cavity length and potentially misaligning the mirrors. This can lead to frequency drift and reduced output stability. The thermal expansion coefficient and operating temperature range are specified to help assess suitability for different environments.
Regular inspection and cleaning of mirror surfaces are necessary to prevent contamination and scattering losses. Alignment should be checked periodically, especially after temperature changes or mechanical shocks. If output power or beam quality degrades, it may indicate misalignment or damage, requiring professional service.
