A room temperature CW NdPP laser at 1.051 and 1.32m pumped by Ar+ laser has been operated. Low threshold operation in a semi-concentric resonator was obtained. The lowest threshold absorption power was 1 mW. Maximum output power for a single transverse mode was 2 mW. Using the laser oscillation data, the stimulated emission cross-sections were determined as follows: 1.05=1.1×10-19cm2, 1.32=2.2×10-20cm2. Laser relaxation oscillation has been studied and a plot of relaxation oscillation frequency as a function of excess threshold [ratio of pumping power is given. Threshold pumping power intensity as a function of crystal length at different output power has been calculated.
