Coherence Time Measurement of Picosecond Pulses Using Reverse Saturable Absorption in Lead Phthalocyanine

Abstract:	The coherence time measurement of picosecond pulses using counter-running pump probe technique in reverse saturable absorption material of lead phthalocyanine were studied. The coherence time of 23ps, 532nm Nd∶YAG laser pulses is 9ps. The experimental results and theoretical analysis show that two beam coherent effect increases the reverse saturable absorption of lead phthalocyanine.

Keywords:	lead phthalocyanine reverse saturable absorption coherence time
