LASER OSCILLATION COOLING DEVICE

摘要

A laser oscillation cooling device (100) is provided with: a light emitting section (1) that emits laser excitation light (Z1); a laser excitation section (2), which emits laser light (Z2) by exciting the laser excitation light (Z1), and which locally generates heat; a storage tank (3) capable of storing an extremely low temperature liquid (L); a pressurizing section (31) that brings the extremely low temperature liquid (L) into a sub-cool state by pressurizing the inside of the storage tank (3); and a jetting supply section (4) that removes heat from the laser excitation section (2) by jetting the extremely low temperature liquid (L) in the sub-cool state to the laser excitation section.
