Frequency converted Lasers

Narrow-linewidth continuous-wave (CW) lasers at visible or ultraviolet (UV) wavelengths have various important applications in the fields of atomic and molecular physics, measurement, communication, biology, etc. In the quantum simulation experiment, high-power 532nm lasers with ultra-low frequency noise can be operated as optical lattice trap, providing enough trap depth for ultra-cold atoms and improving the signal-to-noise ratio of atoms. Besides the visible lasers, high-power CW ultraviolet lasers have been widely needed in the experiments of laser cooling, clock frequency detection, ionization, etc. For example, the long-range interaction of Rydberg atoms has a great advantage in quantum information, Rb can be excited to Rydberg state by single-photon process with 297 nm. The logic ion 9Be+ should be cooled with 313 nm in quantum simulation, and could be used for cooperative cooling of 27Al+ in the optical clocks. In the lithographic process, 390 nm at watt level can obviously reduce the exposure time.
Precilasers provides total solutions for the needs of wavelengths. The standard frequency converted schemes include single-passing second-harmonic-generation(FL-SSHG)、single-passing third-harmonic-generation(FL-STHG)、single-passing sum-frequency-generation(FL-SSFG)、single-passing difference-frequency-generation(FL-SDFG)、second-harmonic-generation(FL-RSHG)and forth-harmonic-generation(FL-FHG)in resonant cavities. With these nonlinear-processes, we can almost achieve wavelength from 266 nm  to 4000 nm.
