Abstract

Among other applications, Q-switched, single-mode and high energy Ho:YAG lasers are useful tools in temperature-jump experiments designed for biophysical research. But if pulse energies of 200 J at one microsecond pulse widths or shorter are to be generated in a single oscillator, the damage threshold of the optical coatings is likely to be exceeded. Experiments with an oscillator/amplifier system show that the saturation fluence of Cr,Tm,Ho:YAG amounts to 2.3J/cm² and that a small signal gain coefficient of 0.15/cm can be obtained at moderate pump densities. This suggests the use of extracavity amplification if high power holmium pulses are required.
