Abstract
Laser light emission across a wide bandwidth emission spectrum is enabled in a laser device equipped with solid gain media. The laser device is equipped with: a resonator; a plurality of solid gain media, having fluorescent spectra that at least partially overlap with each other, provided within the resonator; and pumping means, for pumping the plurality of solid gain media. The entire fluorescent spectrum width of the plurality of solid gain media is greater than the fluorescent spectrum width of each solid gain medium.
Claims18
A laser device, comprising:
- a resonator;
- a plurality of solid gain media, having fluorescent spectra that at least partially overlap with each other, provided within the resonator;
- and
- pumping means, for pumping the plurality of solid gain media;
- wherein:
- the entire fluorescent spectrum width of the plurality of solid gain media is greater than the fluorescent spectrum width of each solid gain medium, and
- the pumping means is equipped with at least one pumping light source, a pumping light beam output from the at least one pumping light source enters the plurality of solid gain media, and simultaneously pumps at least two of the plurality of solid gain media.
