Paper Abstract
We report on a high-power diode laser pump source for diode-pumped alkali lasers (DPAL), specifically rubidium alkali
vapor lasers at 780nm, delivering up to 100W/bar with FWHM spectral line width of 0.06nm (~30GHz). This pump is
based on a micro-channel water-cooled stack with collimation in both-axes. Wavelength-locking of the output spectrum
allows absorption in one of the very narrow resonance lines of the atomic rubidium alkali vapor. To achieve these
results, research was conducted to deliver the highest performance on all key components of the product from the diode
laser bar which produces the optical power at 780nm to the external Bragg gratings which narrow the spectrum line
width. We highlight the advancements in the epitaxy, device design, beam collimation, grating selection, alignment,
tunability and thermal control that enable realization of this novel pump-source for DPALs. Design trade-offs will be
presented.
