Laser light source and photoelectron microscope |
| abstract |
Provided are a high-energy and high-powered laser light source and a photoemission electron microscope using the laser light source. The laser light source 2 is intended for use in the photoemission electron microscope for emitting a quasi-continuous wave laser 7 and includes: a first laser light source 100 configured to emit a continuous wave coherent light 100a, an optical resonator 110 including an optical path in which the continuous wave coherent light 100a circulates and including a non-linear optical element 114 disposed on the optical path, and a quasi-continuous wave light source 120 configured to emit a quasi-continuous wave coherent light 120a having a wavelength shorter than that of the continuous wave coherent light 100a and having a near rectangular output waveform. When the quasi-continuous wave coherent light 120a is incident on the non-linear optical element 114 from outside the optical resonator 110 while the continuous wave coherent light 100a is entering the optical resonator 110 to circulate in the optical path, the quasi-continuous wave laser 7 having a wavelength shorter than that of the quasi-continuous wave coherent light 120a is emitted from the non-linear optical element 114. |
