Abstract

Owing to their inherently low frequency and intensity noise, small size, high reliability, and potentially high power, monolithic diode-laser- pumped solid-state lasers are very attractive for applications in the fields of communication and precision laser metrology. In these applications the laser frequency should be absolutely stabilised. Molecular cesium has been studied by several groups for 1064nm Nd:YAG laser frequency- stabilisation application. Owing to different host material, output frequency of Nd lasers is slightly different at room temperature, such as about 55.6 GHz frequency difference between Nd:YAG and Nd:YVO₄. It has been hoped that the absorption spectra of molecular cesium are well known near 1064nm in details to help absolutely stabilise frequency of Nd:YVO₄ or other Nd lasers.
