ABSTRACT:
An optically-controlled lens is used to stabilize a plano-plano optical resonator. The lens is made of a material whose shape, refractive index, or both can be changed by optically-induced localized heating. A control light source is provided to irradiate the lensing element and cause the required heating. In an optically-pumped laser, the pump light may function as the control light. For a longitudinally-pumped Nd:YAG laser, a suitable optically-controlled lens can be tailored out of GaAlAs to give the appropriate amount of optical absorption at the pump wavelength, while being transparent to the lasing wavelength.
