S. Khodja et al., BROAD-BAND PUMP WAVELENGTH TUNING OF A LOW-THRESHOLD N-(4-NITROPHENYL)-L PROLINOL NEAR-INFRARED OPTICAL PARAMETRIC OSCILLATOR, Applied physics letters, 67(26), 1995, pp. 3841-3843
We report the pump wavelength tuning of a low threshold N-(4-nitrophen
yl)-L-prolinol based nanosecond pulsed optical parametric oscillator i
n the near infrared. A broad tuning range from 1 to 1.5 mu m correspon
ds to a limited pump wavelength excursion from 583 to 590 nm and a rec
ord low oscillation threshold of the order of 0.5 MW cm(-2). (C) 1995
