Abstract
The invention discloses a three-dimensional optical parametric oscillation terahertz wave radiation source, including a pump source, MgO:LiNbO 3 Crystal, pump light recycler, and set in MgO:LiNbO 3 Mirrors around the crystal; the plane of the first pump light and the tenth pump light propagation is the plane determined by the X axis and the Y axis, and the Z axis is perpendicular to the plane of the first pump light and the tenth pump light propagation, The propagation direction of the pump light emitted from the pump source is the negative direction of the X axis, and the propagation direction of the terahertz wave is the positive direction of the Y axis. The three-dimensional optical parametric oscillating terahertz wave radiation source provided by the present invention has the following advantages: the pump light can be recycled to generate multiple beams of terahertz waves, and the energy of the terahertz waves can be effectively increased. By changing the angle between the pump light and the Stokes light, frequency-tuned terahertz waves can be obtained. The tuning method is simple and the operation is flexible. Terahertz waves perpendicular to MgO:LiNbO 3 The crystal emits without any coupling output device, which effectively reduces the output loss of the terahertz wave.
Description
technical field [0001] The invention belongs to the technical field of terahertz wave applications, and in particular relates to a three-dimensional optical parametric oscillation terahertz wave radiation source. 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.
