High Power Broadly Tunable Piscosecond IR Laser System for Use in Nonlinear Spectroscopic Applications.
Abstract
A picosecond laser system which 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 amplification in potassium titanyl phosphate. The non-linear optical processes are driven by a regeneratively amplified Ti:sapphire laser which produces 1.7 ps pulses at a repetition rate of 1 kHz. Energies as high as 40 microJ and 12 microJ have been achieved over the signal, 1.02-1.16 micrometers, and idler, 2.6-3.7 micrometers, tuning ranges, respectively. The IR beam temporal and spatial characteristics are also presented. jg
