Abstract
The general theoretical requirements for making multisurfaced (resonant) reflectors frequency-tunable are described. Specifically, reflectors that can be used to stabilize and control the lasing spectrum of ruby lasers are considered. Fabry-Perot ring analysis showed that a four-surface reflector (two parallel sapphire flats) with a spacer (stellite) having close to the ideal thermal expansion coefficient, for thermal frequency tunability, could be used to continuously tune a ruby laser near 6944 Å more than 0.3 Å with a spectral width less than ±0.01 Å.
