摘要：

We discuss new possibilities for the measurement of short laser pulses with the aid of liquid crystals: the competingly acting waves (CAW) method and the linear-optical pulse overlap (LOPO) method. CAW is a non-interferometric method providing both the peak energy density of a pulse and its duration in a simple, single shot measurement. LOPO allows measurement of ultra-short pulse duration with no need for nonlinear optical materials and phenomena. We also show the possibility of utilising the electrically controlled birefringence of liquid crystals to replace the opto-mechanical delay lines, (C) 2000 Elsevier Science B.V. All rights reserved.
