Abstract

Water can be used as a passive shutter for Q-switched erbium lasers. The switching mechanism induced in water under irradiation by 2.79- and 2.94-μm erbium laser light has been studied. It can be explained with a model based on evaporation. Time constants have been measured with a CW HeNe laser at 3.391 μm. The velocity of the vaporization front is about 10 m/s. This value leads to rise and fall times on the order of 10 μs in the given geometry
