Ti: Al2O3 excitation multi-wavelength laser oscillation device

摘要

(57) [summary] (modified with) [purpose] is small, to realize an apparatus which can simplify the adjustment at the time of wavelength variable. [Configuration] is a resonance medium via an excitation light focusing optical system 1 input light Ti: is allowed to enter the Al ₂ O ₃ crystal 5, The Ti: Al ₂ O ₃ and is incident on the light excited from the crystalline 5 in the resonator composed of the high reflection mirror 2 and an output mirror 7, The In the excitation light causes repeated reflections between the resonator to be transmitted through the output mirror of the resonator, Ti outputs to enhance its strength: the Al ₂ O ₃ pumping multi-wavelength laser oscillator, the resonator high reflection mirror and output mirror constituting form a plurality of dielectric reflection film having only a high reflectance for a specific wavelength on one side of the mirror base.
