Paper Abstract

Efficient laser emission of flashlamp pumped Nd:YAG and Nd:YAP rods at a wavelength of 1.444 micrometers (1.434 micrometers ) is reported. This wavelength is of particular interest for medical applications due to the high water absorption coefficient of 26 cm-1. A maximum average output power of 100 W at pulse energies of 5.5 J and overall efficiencies of 1.3% was achieved. The 1.444 micrometers performance as well as the output characteristics at 1.064 micrometers and 1.32 micrometers of Nd:YAG were investigated for different pump cavity reflectance materials and spectral filters as a function of doping concentration and rod diameter. The physical properties of the 1.444 micrometers emission line are discussed.
