Ra. Ganeev et T. Usmanov, STUDY OF CONTINUOUS FREQUENCY TUNING IN A PICOSECOND NEODYMIUM GLASS-LASER IN THE UV REGION, Optics and spectroscopy, 85(2), 1998, pp. 322-325
The study of the process of frequency summation in KDP crystals involv
ing emission of optical parametric oscillators and the second harmonic
of a picosecond neodymium laser is reported. The process produces rad
iation in the UV region.
