title: High-power tunable narrow-linewidth Ti:sapphire laser at repetition rate of 1 kHz.
abstract: We report a high-power tunable narrow-bandwidth Ti:sapphire laser at a repetition rate of 1 kHz. The spectral linewidth of 0.4 pm with wavelength tuning range from 780 nm to 820 nm is obtained by a spectrum-compressing technique that consists of one grating and four fused silica prisms in the oscillator cavity. This narrow-bandwidth seed from the oscillator is further amplified to 6.5 W with pulse duration of 16 ns under the pumper power of 22 W. This high-power laser with narrow linewidth is candidate for isotope separation and accuracy spectrum analysis.
