Abstract
A laser oscillation device includes: a refrigerant container; at least one cartridge which is attached to the refrigerant container and which includes a laser gain medium and an incidence path section for guiding laser seed light to the laser gain medium; at least one nozzle for spraying a refrigerant to the laser gain medium, the at least one nozzle being disposed inside the refrigerant container, and a vacuum heat insulating container housing the refrigerant container inside and forming a vacuum insulation layer on an outer peripheral side of the refrigerant container. The cartridge is disposed so as to be insertable and removable with respect to the refrigerant container along a longitudinal direction of the laser gain medium.
