Theoretical Analysis on scanning spectral filter based on the bi-refraction electro-optical interferometer for pulse contrast improvement in femtosecond laser

A spectral scanning filter method to improve the pulse contrast in the femtosecond chains is proposed, which is made using of the character that the instantaneous frequency varies with the time approximately linearly for the chirped pulse in the time-frequency domain. A spectral scanning filter base...
