Optical design of a frequency-doubled Nd:YAG laser

The design and laboratory manipulation of the optical resonator of a frequency-doubled Nd:YAG laser has been aided by a unique computer program written for the desk-top HP 9820 calculator-plotter. The program is a self-consistent treatment of Gaussian mode propagation and includes the thermooptical effects of intracavity elements. The optimization of the frequency-doubled laser is greatly aided by use of the computer program. A listing and narrative of the computer program and its use in optimization of the frequency-doubled Nd:YAG is available upon request.
