Matisse 2 for Lithium Cooling

Power at 671 nm

Sirah’s Matisse 2 ring laser is a powerful tool for cooling Alkali-metal atoms. We tested and optimized the Matisse Titan:Sapphire performace at a wavelength of 670.9 nm. Using a 15 W Millennia as pump laser we demonstrated above 1500 mW at the Lithium resonance. So, the Titan:Sapphire is now a useful alternative to the dye laser operation of the Matisse. The linewidth of the laser os 50 kHz, with low intensity noise, better than 0.25% rms. For details check here.
