Abstract :
The second harmonic generation (SHG) signal converted from the 22 /spl mu/m input wavelength of free electron laser (FEL) is observed using a non-birefringent CdTe crystal and a birefringent Te crystal. The conversion efficiency of SHG is obtained to be 2.2/spl times/10/sup -2/ % (/spl sim/7.3/spl times/10/sup -5/ %/(MW cm/sup -2/)) in CdTe crystal and 0.40% in Te crystal experimentally. The experimental phase-matching angle of Te crystal is 9.62/spl deg/.
