Problems solved by technology
Obviously, the problems faced at high pump power have not been addressed, and the output orthogonal polarization dual wavelengths have not been precisely regulated. In addition, based on the Nd 3+ Doped MgO:LiNbO 3 The crystal is periodically polarized, and the laser gain and frequency conversion are shared by the same crystal. The self-pumping phenomenon is also the future development direction.

Abstract
This disclosure discloses a Nd:MgO:LiNbO based 3 Orthogonal polarization dual-wavelength freely adjustable switching laser of the crystal, laser diode pumping source, 1084nm resonant cavity full reflection mirror, polarizer, Nd:MgO:LiNbO 3 Crystal and output mirror; laser diode pump source is used to emit pump light; 1084nm resonant cavity mirror is used to reflect Nd:MgO:LiNbO 3 The 1084nm laser emitted by the crystal makes the 1084nm laser oscillate in the 1084nm resonant cavity; the polarizer is placed at the intersection of the 1084nm and 1093nm resonant cavity, placed at an angle of 45 degrees to the horizontal optical path, and is used to separate orthogonally polarized dual wavelengths; Nd:MgO :LiNbO 3 Used to emit 1084nm and 1093nm lasers; the output mirror is used to output 1084nm and 1093nm lasers; the electro-optic crystal and the 1093nm total reflection mirror are sequentially placed on the reflection optical path of the polarizer; The polarization state of the 1093nm laser is changed under the action of the 1093nm laser; the 1093nm total reflection mirror is used to reflect the 1093nm laser, so that the 1093nm laser passes through the electro-optic crystal twice and oscillates in the 1093nm resonant cavity.
Description
technical field [0001] The invention relates to the field of lasers, in particular to a laser based on Nd:MgO:LiNbO 3 Orthogonal polarization dual-wavelength freely tunable switching lasers in crystals. Background technique [0002] The 1μm orthogonally polarized dual-wavelength laser has broad prospects and research and application value in material processing, biomedicine, instrument precision measurement, laser ranging, and laser interferometry. It is an important branch of the laser field. Therefore, how to adjust the output wavelength Precise regulation has become one of the research focuses. In recent years, Nd:YLF, Nd:YAP, Nd:GdVO based on doped neodymium ions 4 And lasers doped with ytterbium ions Yb:KGW, Yb:GMB and other linear crystals have become the most widely used technical means to obtain orthogonally polarized dual-wavelength lasers. Ions have vertical, orthogonal polarization states. Therefore, how to precisely control dual wavelengths is a very importan...
