Abstract
Official abstract text for this publication.
When the laser light source is caused to standby, the temperatures of semiconductor lasers are changed by approximately 3° C. from the temperature when the laser light source is always being used. With a temperature change of approximately 3° C., the wavelengths of the laser light generated by the semiconductor lasers change approximately 0.3 nm. This change hardly has any effect at all on optical fiber amplifiers, but the conversion efficiencies at the respective wavelength conversion elements of the wavelength conversion optical system change, and, particularly, deep ultraviolet light is hardly generated at all any longer. Therefore, even while the laser light has been made incident to the wavelength conversion optical system, there is no longer damaging of the wavelength conversion elements. Therefore, it is possible to provide a laser light source standby method that is able to shorten the start up time of the laser light source.
First claim
Opening claim text (preview).
The invention claimed is: 1. A laser light source standby method for a laser light source that uses optical fiber amplifiers to perform light amplification of laser light generated from semiconductor lasers and then forms deep ultraviolet light by means of a wavelength conversion optical system that uses a plurality of laser oscillating parts that are configured to form deep ultraviolet light, the method comprising: shifting, during standby, a relative relationship of a timing of…
