Laser with Wavelength 0.589 micrometer ('Sodium Wavelength Laser').

摘要

This report results from a contract tasking General Physics Institute of the Russian Academy of Sciences as follows: The objective of this project is to develop a laser system based on F2(-) color centers in LiF crystals with frequency doubling, which produces from 10 to 40 Watts average output power radiation at 589 nm, the wavelength of the sodium fluorescence, and with the spectral width of the radiation being several hundred megahertz. It is pumped by a high power Nd:YAG laser. This is a continuation of an effort that has been going on for two years.
