High Power 7-GHz Bandwidth External-Cavity Diode Laser Array and Its Use in Optically Pumping Singlet Delta Oxygen

Abstract

Using a 14-mm thick volume Bragg grating, spectral bandwidth of a diode laser array is narrowed to 7 GHz (FWHM). The total output power is 13.5 W, of which 86% is in the 7-GHz band. With such a narrow bandwidth, it is possible to temperature tune laser frequency across O(2) X(3) Pi -> b(1) Sigma(+) absorption line at 763.8 nm, efficiency generating O(2)((1)Delta) molecules.
