Embodiment 1

[0015] Such as figure 1 As shown, the BaTeMo of the present invention 2 o 9 A crystal all-solid-state Raman self-frequency doubling yellow light laser, including a pump light source 1, an aperture 2, an optical rotator 3 and a resonant cavity. Electro-optic Q-switched Nd:YVO 4 The laser 1, the diaphragm 2, the optical rotator 3 and the resonant cavity are arranged together in sequence. The resonant cavity includes input mirror 4, BaTeMo 2 o 9 Crystal 7, output mirror 5 and filter 6, BaTeMo 2 o 9 The crystal 7 is arranged between the input mirror 4 and the output mirror 5 , and the filter 6 is arranged outside the output mirror 5 .

[0016] The central wavelength of the pump light source 1 is 1064nm, which can be electro-optic Q-switched, and the pump source can use Nd 3+ YAG, Nd 3+ GGG and other electro-optic, acousto-optic Q-switched lasers instead. This embodiment uses electro-optic Q-switched Nd:YVO 4 A laser is used as the pump light source.

Abstract

The invention provides an all solid Raman self frequency doubling yellow laser of BaTeMo2O9 crystal, which comprises a pump light source, a diaphragm, a polarization apparatus and a resonant cavity, wherein the pump light source, the diaphragm, the polarization apparatus and the resonant cavity are orderly arrayed, the resonant cavity comprises an input lens, BaTeMo2O9crystal, an output lens and a filtering plate, the BaTeMo2O9 crystal is arranged between the input lens and the output lens, and the filtering plate is arranged on the outer side of the output lens; and the two end of the BaTeMo2O9 crystal are all plated with antireflection films of 1064nm, 1178nm and 580nm, and the input lens and the output lens are coated with films. The all solid Raman self frequency doubling yellow laserprovided by the invention adopts the BaTeMo2O9 crystal to replace the Raman crystal and frequency doubling crystal. The all solid Raman self frequency doubling yellow laser utilizes the resonance outside the cavity to realize the Raman self frequency doubling in the crystal, realizes the Raman conversion of 1064nm fundamental frequency light so as to obtain Raman light about 1178nm far away, and realizes the frequency doubling of the Roman light to generate the yellow laser of 589nm; and moreover, the all solid Raman self frequency doubling yellow laser has the characteristics of compact structure, high efficiency and stability.

Description

technical field [0001] The present invention relates to a kind of adopting BaTeMo 2 o 9 A crystal all-solid-state self-frequency doubling yellow light laser belongs to the technical field of all-solid-state lasers. Background technique [0002] The yellow-orange band (560-600nm) laser is close to the wavelength sensitive to human eyes (555nm), suitable for laser display and lighting, especially for geodesy under foggy conditions and the use of such collimation occasions. Yellow laser has important applications in medicine, radar, spectroscopy, oceanography, information storage and laser navigation, and has become one of the research hotspots in the field of lasers. However, since it is currently impossible to generate yellow light through the direct transition of activated ions, it is more difficult to generate laser light in the yellow light band than other visible light bands. At present, it is an effective method to use the stimulated Raman scattering (SRS) effect of t...
