Tunable titanium jewelry laser of 588nm yellow light pump

Abstract

The invention discloses a tunable titanium jewelry laser of a 588nm yellow light pump. The laser is characterized in that a pump light is emitted by a 808nm or 880nm laser diode pump source; the pump light are focused at the interior of an Nd:YVO4 crystal through a transmitting energy fiber and a coupling lens, population inversion is carried out, and a laser with the wavelength of 1064nm is generated under the effect of a resonant cavity composed of a resonant cavity reflector and a yellow light output lens; one-order strokes with the wavelength of 1176nm are generated when the intensity exceeds the Roman threshold value; a 588nm yellow light is generated under the effect of a yellow light frequency doubling crystal, the yellow light is focused in a titanium jewelry crystal through a coupling focus lens, pumping is carried out on the titanium jewelry crystal, and population inversion is carried out, thus generating a spontaneous radiation photon; and titanium jewelry laser oscillation is formed under the effect of the titanium jewelry laser resonant cavity composed of a titanium jewelry laser full reflection lens and an output lens, and the tunable output of the wavelength is realized through regulating the horizontal direction angle of the titanium jewelry laser full reflection lens under the effect of a dispersion element.

Description

technical field [0001] The invention relates to lasers in the field of laser technology, in particular to a 588nm yellow-light-pumped tunable titanium sapphire laser. Background technique [0002] Due to its extremely wide tunable band (600-1100nm) and excellent crystal performance, Ti:Sapphire laser has become an important gain crystal for all-solid-state tunable lasers. The disadvantage of its wide tunable wavelength is that the lifetime of the upper energy level is very short, about 3.2 μs at room temperature, and the lifetime of the upper energy level will be significantly shortened as the temperature of the crystal increases, which affects the operation of the laser. It brings great disadvantages, especially in the case of high-power pumping, its thermal effect will make the lifetime of the upper energy level shorter and easily lead to temperature quenching. The absorption band of Ti:Sapphire crystal is 400-630nm, and the absorption peak is around 490nm. Traditional Ti...
