The invention provides a titanium sapphire laser amplifier, which comprises a pumping laser, a titanium sapphire crystal, a multi-path amplifier, a laser seed source and a synchronous time delay. The titanium sapphire laser amplifier is characterized in that a pumping light half wave plate is added into an output light path of the pumping laser, and a pumping light quarter wave plate and a pumping light reflecting mirror are sequentially added into a transmission light path of the titanium sapphire crystal. The titanium sapphire laser amplifier has the advantages that the transverse gain of the titanium sapphire crystal can be effectively reduced, so the parasitic oscillation of the titanium sapphire is well inhibited, in addition, the absorption rate of the titanium sapphire crystal on the pumping light can be improved, and the seed light amplification efficiency is improved. The titanium sapphire laser amplifier has the characteristics that the regulation is convenient, simplicity and ...

The invention belongs to the technical field of laser, and provides a 213nm ultraviolet light output method and system. The method comprises the steps of controlling a laser to generate a laser pulse, enabling the laser pulse to generate 532nm frequency-doubled light after passing through a frequency doubling crystal, and enabling the 532nm frequency-doubled light and residual 1064nm fundamental frequency light to generate 266nm laser pulse after passing through a quadruplicated frequency crystal, and enabling the 266nm laser pulse and the residual 1064nm fundamental frequency light to be irradiated to a frequency quintupled crystal so as to generate 213nm ultraviolet light. According to the method provided by the invention, the problem that polarization needs to be converted in the process of generating the 213nm laser pulse by performing sum frequency on the frequency doubled light and the frequency tripled light can be avoided.
