摘要： PROBLEM TO BE SOLVED: To provide a laser device in which a pressure regulator is connected to a vacuum container where laser light is emitted and a cavity part, and regulates the pressure in the vacuum container and the pressure in the cavity part to substantially equal pressure values to suppress strain of a transmission-type optical component. SOLUTION: As the pressure in the vacuum container 1 rises by excitation of the laser light, the pressure in a right chamber 14b of a cylinder 14 connected to the vacuum container 1 rises. Then, pressing force is applied to a piston 15, which moves to the side of a left chamber 14a of the cylinder 14. Consequently, while the pressure in the cavity part 29 in a block 4 connected to the left chamber 14a rises, the pressure in the vacuum container 1 falls. When the pressure in the vacuum container 1 and the pressure in the cavity part 29 eventually become substantially equal to each other, the piston 15 stops. COPYRIGHT: (C)2011,JPO&INPIT
