Abstract

A new configuration of 589 nm yellow laser with a single LD pump source and coaxial double crystal was proposed. When the incidence pump power was 1.5 W, 54 mW yellow laser at 589 nm was obtained, the optical to optical conversion efficiency was 3.6%, and the laser instability was about 5%. A conventional method for 589 nm laser was also tested under the same conditions, only 15 mW yellow laser was obtain. The configuration of single pump source and coaxial double crystals is compact and flexible, which can be used in many sum frequency lasers, such as the 491, 488, 593.5, 555 and 500.8 nm laser, and so on.
