Title: Gas laser device
Inventor: KAWAGUCHI SHIGERU
IPC: H01S3/03
Filed: 1986-10-09
Abstract: PURPOSE:To quantitatively grasp a change due to time passing in total absorptiv ity of a window and an output mirror and to enable the drawing of laser light in a mode good in symmetric property, by installing a sensor for temperature measurement on the periphery of an uncooled side of a laser light drawing window whose lateral periphery is cooled in a resonator. CONSTITUTION:Since a window 1 is cooled on its lateral periphery, a tempera ture on the periphery (A point) of a side opposite to the cooled surface rises as total absorptivity increases. A change due to time passing in the total absorp tivity can be quantitatively grasped by observing the temperature on the periph ery (A point) of the window 1. It can be more precisely grasped in a real device by measuring the absorptivity at the window and a value of a rise in tempera ture on the periphery in accordance with respective laser outputs and modes. Once the temperature on the periphery (A point) of the window is observed, a period for cleaning or replacing the window 1 can be controlled, so that laser light can be obtained always as expected.
