Measurement Of Nonlinear Absorption Of Intense Laser Pulses By Yvo4 Crystal

We measured the nonlinear absorption coefficient of YVO4 using nonlinear transmittance method. The result is: for wavelength of 800nm, YVO4's nonlinear absorption coefficient is 3.2x10(-3)cm/GW for p polarization and 3.1x10(-3)cm/GW for s polarization; for wavelength of 400nm, YVO4's nonlinear absorption coefficient is 0.17cm/GW for p polarization and 0.16cm/GW for s polarization.
