Stanford University generates 43W of quasi-CW at 780nm for atom interferometry

The Kasevich group at the Stanford Photonics Research Center has demonstrated a 43W quasi-CW laser source at 780nm for laser cooling and manipulation of rubidium.

Published in this month's Optics Letters, Chiow et al. describe a cascaded single pass SHG system using two MgO:PPLN crystals (MSHG1550-1.0-40, Covesion). The system is pumped with two combined 1560nm 30W fiber amplifiers, and by adjusting the relative phase between these two sources, the temporal profile of the 780nm output can be controlled. With a combined pump power of 65W, a peak power of 43W is achieved at 780nm, corresponding to an efficiency of 66%. This high power, high beam quality, narrow linewidth and amplitude modulated source can be applied to large area atom iterferometers for the detection of gravitation waves.
