Abstract

We report the use of GaAlAs laser-diode arrays to pump a cw Nd:YAG laser operating on the 946-nm 4F3/24I9/2 transition. At room temperature, the lasing threshold was reached with 58 mW of absorbed pump power, and, with 175 mW of absorbed pump power, 42 mW of output power at 946 nm was obtained in a TEM00 mode by using 0.7% output coupling. In addition, pumping with an infrared dye laser operating in a pure TEM00 mode was used to investigate the effects of reabsorption loss that are characteristic of the 946-nm laser transition. LiIO3 was used as an intracavity doubling crystal, and 100 μW of blue light was generated by using diode-laser pumping in a nonoptimized cavity.

Normalized slope efficiency (dS/dF of Ref. 13) as a function of the ratio of pump waist to laser waist without reabsorption loss [B = 0, where B = 2N10l/(L + T)] and with reabsorption loss (B = 1.5) at different laser power levels. S is a normalized variable proportional to internal laser power; F is a normalized variable proportional to threshold pump power.
