Optical parametric amplification in a lithium triborate crystal tunable from 0.65 to 2.5 μm

Abstract
We investigate the phase-matching properties and the performances of lithium triborate (LBO) crystals, angle- and temperature-tuned to achieve type-I phase matching for ps, high-power, tunable optical parametric amplification (OPA). A novel retracing behavior was observed in the tuning curves of the LBO OPA.
