An automatically and broadly tunable Ti∶sapphire laser based on the control of LabVIEW is designed, which is implemented by feedback controlling the angle of intracavity birefringent filters (BRF). The feedback signal is generated by LabVIEW program after the laser output wavelength measured by a wavelength meter is obtained. Then the one-to-one relationship between the BRF angle and the laser output wavelength is established based on the measured wavelengths. The BRF angle corresponding to the setting wavelength is calculated and then controlled by LabVIEW procedure, so that the laser wavelength can be automatically tuned without wavelength meter, which simplifies the laser system. With the automatically tunable system, the tuning range of the designed Ti∶sapphire laser is 110 nm.
