Problems solved by technology

Therefore, to obtain dual-wavelength output, two optical parametric oscillators are required; the structure is complex and the development cost is high
[0005] When the traditional difference frequency parameter generator is used, different wavelengths need to be injected with signal light of different wavelengths, which greatly increases the development cost; in addition, the control of the output wavelength is limited by the signal light source that participate

Embodiment 1

[0048] Such as figure 2 As shown, a compact wide-spectrum, independently tunable dual-wavelength parametric oscillator in this embodiment aims at splitting the pump light into two paths whose polarization states are perpendicular to each other, passing through two linear arms placed in a four-mirror ring cavity respectively. In the first crystal 12 and the second crystal 14, the first crystal 12 and the second crystal 14 have different working temperatures or polarization periods. After the pump light acts on it, a dual-wavelength idler light output is generated. The present invention includes:

[0049] The pump laser 1 has a maximum output power of 20W, a central wavelength of 1064nm, and a spot diameter of 1mm after collimation;

[0050] The pump laser 1 and the polarization beam splitter 2 are isolated by a unidirectional isolator 16, so as to avoid the influence of component surface reflection on the pump laser 1 in the subsequent optical path;

[0051] The polarizing b...

Abstract

The invention relates to an optical parameter oscillator, especially relates to a compact broadband spectrum independently-tunable dual-wavelength parameter oscillator and belongs to the field of laser technology and nonlinear optics. The parameter oscillator comprises a pump laser, a polarization beam splitter, a reflector, a first controller, a second controller, a first coupling optical system, a second coupling optical system, a first chamber mirror, a second chamber mirror, a third chamber mirror, a fourth chamber mirror, a first crystal, a second crystal, a first spectroscope and a second spectroscope. According to the invention, an optical parameter oscillation resonant cavity is adopted to realize dual-wavelength outputting; independent tuning of the center wavelength and wavelength intervals of output light can be independently tuned in a broadband spectrum scope. The power of two paths of output light with different wavelengths can be independently tuned. The pump light source is a non-polarization light source. The compact broadband-spectrum independently-tunable dual-wavelength parameter oscillator of the invention has characteristics of being simple in structure, low in cost, reliable in working and convenient in operation.

Description

technical field [0001] The invention relates to an optical parametric oscillator (OPO), in particular to a compact wide-spectrum, independently tunable dual-wavelength parametric oscillator, which belongs to the fields of laser technology and nonlinear optics. Background technique [0002] Dual-wavelength lasers can be widely used in biochemistry, remote sensing detection, spectroscopic physics and other fields. Although there are many ways to generate dual-wavelength laser output, the output characteristics of traditional dual-wavelength lasers are limited by the spectral line width of the laser gain medium, and the tuning range is only GHz; and it is not easy to achieve wavelength interval tuning and relative intensity control. [0003] Optical parametric oscillators and difference frequency parametric generators are effective means to obtain wide-spectrum tunable laser output. When the periodically polarized medium is used as the nonlinear parametric crystal, the wide sp...
