Typical PG501 model tuning curve A microprocessor-based control unit provides hands-free OPG operation and (pump energy: 10 mJ @ 532 nm) exceptional output wavelength reproducibility. Precise temperature stabilization of the nonlinear crystals assures a long-term stability of the output parameters. A built-in pump pulse energy monitor alerts the user if the pump intensity approaches 1.0 the preset value. 0.8

PG501-DFG – UNPRECEDENTED TUNING RANGE UP TO 16 µm

PG501-DFG1 model combines an OPG and difference frequency generator (DFG) 300 into a single unit and features extremely wide wavelength coverage. Tuning range up to 10 µm is achieved by mixing the OPG idler wave at 1.19–1.98 µm with the 250

1064 nm beam of a picosecond Nd:YAG laser in AgGaS crystal. Good OPG output ,µJ 200 2 PG501-DFG1P beam spatial profile and relay imaging (RI) of 1064 nm beam ensure high DFG 150

conversion efficiency, providing up to >300 µJ per pulse in the 3–4 µm range. The Pulse energy 100
