THE LASER RESONATOR FOR LONG PULSE AT TERNARY WAVELENGTHS

摘要

PURPOSE: A laser resonator which forms long pulse laser oscillation of three wavelengths is provided to execute a shutter operation which is dull to a noise by using a shutter using a solenoid coil. CONSTITUTION: A laser cavity(100) is composed of a flash lamp(101) and a neodymium doped yttrium aluminum garnet laser medium(102). The laser medium is composed of a neodymium doped yttrium aluminum garnet rod. The flash lamp transfers light energy to the laser medium according to an electric signal by sealing xenon gas which is dischargeable in the wavelength band of 600-800nm in the neodymium doped yttrium aluminum garnet laser medium. Two total reflection mirrors(104,105) creates the laser of a fixed wavelength for oscillating the laser of 1320nm and 1064nm wavelength. A partial reflection mirror(106) is arranged in the opposite side of the total reflection mirror.
