WIDE-BAND WAVELENGTH-VARIABLE LASER DEVICE

摘要

In a laser apparatus including an excitation light source and a resonator in which a laser medium is disposed between optical paths of a first mirror reflecting light in a desired wavelength band and a second mirror and a first wavelength selecting means is disposed between optical paths of the laser medium and the second mirror, there is provided a wavelength-variable laser apparatus capable of continuously varying the laser oscillation wavelength by using at least a Pr 3+ -doped fluoride glass in the laser medium.
