Abstract
Retracing behavior of phase matching has been observed in the generati on of infrared radiation (1.25-1.85 mum) by both type-I angle-tuned an d temperature-tuned difference frequency mixing of a Nd:YAG laser (106 4 nm) with its second-harmonic pumped dye laser (570-675 nm) in lithiu m triborate crystal. Large spectral acceptance of 49 nm at spectral no ncritical phase-matching point and angular acceptance of 4.0-degrees a t angular noncritical phase-matching point has been obtained.
