Abstract

PURPOSE:To equalize oscillation wavelength to the maximum amplification factor wavelength of amplifying laser glass by using Nd-containing Gd3Ga5O12 as active medium for a laser oscillator and Nd-containing glass as active medium for an amplifier. CONSTITUTION:When excited by a flash lamp, an Nd-containing Gd3Ga5O12 laser 1 is capable of pulse oscillation for mode synchronization and Q-switch operation. The oscillation wavelength thereof is 62mum. A silicate glass amplifier 3 whose maximum amplification factor wavelength is 1.062mum is connected to the upper portion of the optical axis 2 of emission. Further, an amplifier 4 is placed to have a similar relation if required so that high-output pulses can be obtained. High output can be obtained steadily by thus completely equalizing oscillation wavelength to the maximum amplification wavelength of amplifying laser glass.
