Cw ruby laser pumped by a 5145 Å argon laser

Abstract

We describe an argon laser pumped ruby laser system which provides 300 mW in several modes using 2 W of single mode 5145 Å argon laser pump power. By filtering the output with a stabilized Fabry–Perot cavity, single mode outputs of 75 mW or more were obtained. The laser is tunable over a frequency width of 60 GHz about the R1 line at LN2 temperatures, with single mode powers between 10 and 100 mW.
