A picosecond laser system that will generate high-power tunable IR pulses with bandwidths suitable for spectroscopic applications is discussed. The system is based on white-light continuum generation in ethylene glycol and optical parametric amplif ication in potassium titanyl phosphate. The nonlinear-optical processes are driven by a regeneratively amplif ied Ti:sapphire laser that produces 1.7-ps pulses at a repetition rate of 1 kHz. Energies as high as 40 and 12 μ J have been achieved over the signal (1.02–1.16-μm) and idler (2.6–3.7-μm) tuning ranges, respectively. The IR beam temporal and spatial characteristics are also presented. © 1995, Optical Society of America.
