Abstract

The invention relates to a single-frequency continuous wave all-solid-state Ti sapphire laser for realizing automatic broad tuning and a method thereof. The invention aims to settle technical problems of tedious operation, narrow tuning range and low tuning precision in an existing tunable Ti sapphire laser and the tuning method thereof. The single-frequency continuous wave all-solid-state Ti sapphire laser for realizing automatic broad tuning is characterized by comprising a pumping source, a Ti sapphire crystal, a four-lens ring laser resonator, a broadband optical isolator, a birefringence wave filter, an electric-optical standard member, a coupling system, a beam splitter mirror, a wavemeter, a computer, a piezoelectric controller and a piezoelectric rotating motor. According to the single-frequency continuous wave all-solid-state Ti sapphire laser and the method, a Labview automatic control program is used for realizing automatic tuning for output wavelength of the Ti sapphire laser; and an automatic broad tuning device can realize tuning for output wavelength of the all-solid-state continuous single-frequency Ti sapphire laser through setting a target wavelength on a control interface, thereby realizing no requirement for a tedious and complicated operation process and greatly reducing error rate in manual operation.

Description

technical field [0001] The invention relates to a tunable Ti:sapphire laser, in particular to a single-frequency continuous wave all-solid-state Ti:sapphire laser and a method for realizing automatic wide tuning. Background technique [0002] The output spectral range (700-1100nm) of the all-solid-state continuous single-frequency tunable Ti:sapphire laser covers the absorption line bands of alkali metal atoms such as potassium, rubidium, and cesium, so it can be widely used in atomic capture and cooling, atomic clocks, and Bose In atom-based scientific research experiments such as Einstein condensates, quantum memory, optical magnetometers, and atomic force microscopes. In order to make the output wavelength correspond to the absorption bands of different kinds of alkali metal atoms, the Ti:Sapphire laser must have a wide tuning range. At present, people use different means to realize the broadband tuning of Ti:sapphire lasers, but most of the devices used are manual tunin...
