Single-frequency nanosecond-pulsed deep-ultraviolet coherent light source at 252 nm for manipulating silicon atoms resonantly

A frequency-tripled deep-ultraviolet single-frequency nanosecond-pulsed Ti:Sapphire laser injection-locked with a cw single-frequency Ti:Sapphire laser was developed for the laser manipulation of silicon atoms with 252 nm resonant light. The cavity frequency of the slave-laser was controlled dynamically with a piezotransducer mounted on an output mirror to match the optical frequency of the seed laser, so as to minimize the build-up time of the slave-laser. Stable mode matching was achieved and resulted in high stability of the wavelength, making it sufficient for use in silicon atom optics.
