WebThe principle of the laser is based on chirped pulse amplification; a stretched pulse is amplified to the demanded energy, and re-compressed afterwards. This report describes the performed work concerning the design and construc- tion of … WebThe Holland theory group has just come up with a stunning idea for a new kind of laser cooling for use with ensembles of atoms that all “talk” to each other. In other words, the … signal officer army branch

Laser cooling of lithium using relay chirp cooling

WebFeb 17, 2024 · Using frequency-chirped radiation pressure slowing, we precisely control the velocity of a pulsed CaF molecular beam down to a few m s –1, compressing its velocity spread by a factor of 10 while retaining high intensity: at a velocity of 15 m s –1 the flux, measured 1.3 m from the source, is 7 × 10 5 molecules per cm 2 per shot in a single … WebMar 12, 2015 · After detection of a collision, a frequency 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 final data set. 3. the process of self investment
