Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] as attached Figure 1-2 As shown, a high-energy terahertz wave parametric oscillator includes a pump source 1, a first mirror 3, a second mirror 4, a third mirror 6, a P-1th mirror P-1, a P-th -2 mirrors P-2, P-3 mirrors P-3..., P-(N-1) mirrors P-(N-1), S-1 mirrors S-1, S-th mirrors -2 mirror S-2, S-3 mirror S-3..., S-(N-1) mirror S-(N-1), first MgO:LiNbO 3 Crystal C-1, the second MgO:LiNbO 3 Crystal C-2, the third MgO:LiNbO 3 Crystal C-3..., Nth MgO:LiNbO 3 Crystal C-N;

[0035] The pump light 2 emitted from the pump source 1 is reflected by the first mirror 3 and then incident on the first MgO:LiNbO 3 Crystal C-1 generates Stokes light 5 and the first terahertz wave T-1 through the optical parametric effect. Hertzian wave T-1 from the first MgO:LiNbO 3 Vertical emission in crystal C-1;

[0036] From the first MgO:LiNbO 3 The pump light 2 emit...

Abstract

The invention provides a high energy Terahertz wave parametric oscillator which comprises a pump source, a first mirror, a second mirror, a third mirror, a P-1-th mirror, a P-2-th mirror,..., a P-(N-1)-th reflector, an S-1-th mirror, an S-2-th mirror,..., an S-(N-1)th mirror, a first MgO:LiNbO3 crystal, a second MgO:LiNbO3 crystal,..., and an N-th MgO:LiNbO3 crystal. The Stokes power generated by N MgO:LiNbO3 crystals is N times the Stokes power generated by only one MgO:LiNbO3 crystal without considering the pump light loss. N MgO:LiNbO3 crystals can produce N Terahertz waves at the same time. The Terahertz wave power generated by N MgO:LiNbO3 crystals is N2 times the Terahertz wave power generated by only one MgO:LiNbO3 crystal. By changing an angle between pump light and Stokes light, frequency tuned Terahertz waves can be acquired. The tuning method is simple and flexibly operated.

Description

technical field [0001] The invention belongs to the technical field of terahertz waves, and in particular relates to a high-energy terahertz wave parametric oscillator. Background technique [0002] Terahertz wave (Terahertz, referred to as THz), refers to the frequency of 0.1-10THz (1THz = 10 12 The electromagnetic wave in the THz range, whose waveband is between the millimeter wave and infrared in the electromagnetic spectrum, is the transition area between photonics and electronics, and macroscopic theory to microscopic theory. The special position of terahertz wave makes it widely used in basic research fields such as physics, chemistry, astronomy, molecular spectroscopy, life science and medical science, as well as medical imaging, environmental monitoring, material detection, food detection, radio astronomy, mobile communication, satellite Applied research fields such as communication and military radar have great scientific research value and broad application prospe...
