Chirped cooling
WebWe demonstrate a chirp-cooling technique that uses a laser with multiple FM sidebands to slow lithium atoms from initial velocities of as much as 1880 m/s to final velocities near … Webfrequency chirped Doppler cooling pulse is applied that recrystallizes the ion chain and achieves the desired initial temperature for performing sideband cooling. We discard the electron shelving data recorded coincident with the collision event from our nal data set. 3.
