Coherence Time Measurement of Laser Pulses Using Two-Photon Absorption
The coherence time measurement of laser pulse was studied by using counter running pump probe technique in two photon absorption materials. The coherence time of 23 ps, 532 nm laser pulses was measured. The experimental results and theoretical analysis show that additional two photon absorption arises from two beam coherence effect. This method can be applied to other pulse width laser measurement.
