Paper Abstract

The effect of air dispersion on the femtosecond pulsed width is studied in this paper. We present the pulsed width variation with central wavelength, grating period and distance, respectively. Then the air dispersion compensation scheme based on the high-density transmissive grating is put forward to compress the pulsed width of femtosecond laser. The diffracted efficiencies variation with the groove depth and the grating period under the condition of TE and TM polarization state are also given through simulation. The scheme has advantages of compact volume and convenient operation.
