Abstract

A comparison of laser emission in highly doped (2.4- and 3.5-at. %) Nd:YAG crystals is made for conventional 808-nm pumping in F5/24 and resonant pumping at 885  nm in the band that collects the hot transitions Z2R1 and Z3R2 of I9/24F3/24 absorption. A systematic improvement of the laser parameters (slope efficiency and emission threshold) in absorbed power under hot-band pumping is observed, as expected from the reduction of the pump’s quantum defect. Together with the expected reduction of heat generation, resonant hot-band pumping in concentrated components shows prospect for greatly increasing the emission capabilities of the Nd:YAG lasers.
