We developed a high-power tunable picosecond IR laser system suitable for nonlinear spectroscopic investigations. We employ a Ti:sapphire regenerative amplifier that produces 1.9-ps, 17-cm{sup {minus}1}, 800-nm pulses at 1 kHz as a pump source. White-light generation in ethylene glycol and optical parametric amplification in potassium titanyl phosphate are used to produce the IR pulses. The tuning range extends from 2.4 to 3.8 {mu}m in the idler and 1.0 to 1.2 {mu}m in the signal. A total efficiency (signal plus idler) as high as 20{percent} was achieved. The spatial, spectral, and temporal characteristics of the IR beam are presented along with vibrational sum-frequency spectra from a glass/octadecyltrichlorosilane/air interface. {copyright} {ital 1996 Optical Society of America.}
