Abstract
We describe a method for frequency narrowing commercial high power diode la sers from 2 to 0.1 nm bandwidth with modest loss of power (< 2 dB). The res ulting laser light is well suited for spin-exchange optical pumping, and we demonstrate that the polarization produced by a 2.5 W narrowband laser exc eeds that of a 15 W array by 40% in our optical pumping system.
