Abstract
A new incoherent Kerr shutter is demonstrated. It utilizes nanosecond optical pulses from an optical parametric oscillator (OPO) that has a broad bandwidth. Through the use of abeta-BaB(2)O(4) crystal, the OPO has a coherence time of 60-800 fs and shows wide wavelength tunability from 410 to 2600 nm. Kerr relaxation time constants for CS(2) and nitrobenzene are the same as those cited in previous works. We also show, for the first time to our knowledge, a 100-fs response for a nitrobenzene solution of 4-(N,N-diethylamino)-beta-nitrostyrene at a 740-nm idler wavelength.
