Abstract

The invention relates to a single-frequency continuous wave tunable Ti sapphire laser based on birefringence etalon locking. The single-frequency continuous wave tunable Ti sapphire laser comprises a pumping source, a light beam coupling system located on an emergent light path of the pumping source and a laser resonant cavity located on an emergent light path of the light beam coupling system. A birefringence etalon forming a certain included angle with a main light path is arranged in the laser resonant cavity; a plane mirror, a first lens, a quarter-wave plate and a polarization beam splitter are sequentially arranged on a reflection light path of the birefringence etalon; a second lens and a first photoelectric detector are arranged on a reflection light path of the polarization beam splitter; a third lens and a second photoelectric detector are arranged on a transmission light path of the polarization beam splitter; the output ends of the first photoelectric detector and the second photoelectric detector are connected with the servo controller; the signal output end of the servo controller is connected with the galvanometer motor; and the birefringence etalon is adhered to a rotating shaft of the galvanometer motor. According to the invention, the influence of additional modulation signals on the noise characteristics of the laser can be avoided, and the low-noise tunable Ti sapphire laser is realized.

Description

technical field [0001] The invention relates to the technical field of titanium sapphire lasers, in particular to a single-frequency continuous wave tunable titanium sapphire laser based on birefringent etalon locking. Background technique [0002] The single-frequency continuous wave tunable Ti:sapphire laser developed based on titanium-doped sapphire crystal has low intensity noise, high stability, good beam quality, and the output laser spectral range can cover transition absorption lines of alkali metal atoms such as potassium, rubidium, and cesium. (700nm-1000nm red light and near-infrared band) and other excellent properties, so it is widely used in scientific research fields such as atom-based cold atom physics and quantum optics. In these atom-based research fields, it is often necessary to precisely adjust the output frequency of the laser to precisely match the absorption line of the atomic transition, which requires the Ti:Sapphire laser to have a certain frequenc...
