Abstract

The invention relates to an all-solid-state deep ultraviolet laser, in particular to a monocrystalline-diamond continuous wave tunable deep ultraviolet laser. The monocrystalline-diamond continuous wave tunable deep ultraviolet laser is provided with a 456nm single-frequency blue-light laser, a transverse mode matching lens, a first laser resonator mirror, a second laser resonator mirror, a third laser resonator mirror, a fourth laser resonator mirror, a laser gain medium, a frequency doubling crystal, a photodiode and a PDH (Pound-Drever-Hall) controller. The 456nm single-frequency blue-light laser, the transverse mode matching lens, the first laser resonator mirror, the frequency doubling crystal and the second laser resonator mirror are arranged on a first optical axis sequentially from left to right, and the third laser resonator mirror, the laser gain medium and the fourth laser resonator mirror are arranged on a second optical axis sequentially from left to right; the photodiode is located on the left rear side of the first laser resonator mirror, and the PDH controller is connected with the photodiode and the fourth laser resonator mirror; the first optical axis is parallel to the second optical axis. The all-solid-state deep ultraviolet laser is small in size, high in efficiency, long in service life, good in beam quality, easy for system integration and easily practical.

Description

technical field

[0001] The invention relates to an all-solid-state deep-ultraviolet laser, in particular to a single-crystal diamond continuous-wave tunable deep-ultraviolet laser based on single-frequency blue light resonance pumping. Background technique

[0002] Laser Raman Spectroscopy (LRS) is an important tool for studying the molecular vibration and molecular structure of substances. With the significant progress in material science, laser, synchrotron technology and nanotechnology, LRS has become more and more important in physics, chemistry, biology and materials science. and other fields are increasingly widely used. Conventional LRS uses a laser with a wavelength greater than 400nm as the excitation source, which usually faces the problems of fluorescence interference and low sensitivity. However, Deep Ultraviolet Laser Raman Spectroscopy (DUVLRS) uses a deep ultraviolet excitation source. When the excitation wavelength is less than 260nm , it can effectively sol...
