LASER CHAMBER, SOLID-STATE LASER DEVICE, AND PHOTOACOUSTIC MEASUREMENT DEVICE

WIPO Patent Application WO/2015/040965

A1

This invention provides: a laser chamber that, with minimal reduction in excitation energy efficiency, is designed so as to be able to be separable; a solid-state laser device that contains said laser chamber; and a photoacoustic measurement device that contains said solid-state laser device. This laser chamber (13) accommodates a laser rod (11) and a flash lamp (12). An upper frame body (51) and a lower frame body (52) can be separated, in the direction in which the laser rod (11) and the flash lamp (12) are adjacent, at prescribed separation positions. A diffusing material (54, 55) constituting a reflective surface is provided inside the upper frame body (51) and the lower frame body (52). Said diffusing material (54, 55) can be separated, in the direction in which the laser rod (11) and the flash lamp (12) are adjacent, at positions where the reflective surface intersects a straight line that, in a cross-section perpendicular to the lengthwise direction of the laser rod (11), passes through the flash lamp (12) and is perpendicular to a straight line that connects the center of the laser rod (11) and the center of the flash lamp (12).
