Product Description
QTekLaser products with model No. QT-LASR-SHG-xxx-x-x-x-xxx-x are a series of fiber laser products using second-harmonic generation (SHG), providing all-fiber narrow-linewidth polarization-maintaining (PM) laser sources at wavelengths ranging from 765 to 805 nm and at a power level up to 4 W. Products with with model No. QT-LASR-BSHG-xxx-x-x cavity-free technology provide directly collimated narrow-linewidth laser sources at wavelengths ranging from 506 to 540 nm and 765 to 805 nm and power levels up to 22 W. A smart internet-of-things (IoT)-based control system is adopted to enable user-friendly interface. The system is packaged in a typical industrial 3 or 4U 19" rack-mountable chassis.
Applications
- Laser cooling and trapping
- Atomic interferometry
- Quantum sensing
- Quantum computing
Second-Harmonic Generation (SHG)
QTekLaser offers laser systems with extended wavelength range by combining nonlinear frequency conversion technologies. Through second-harmonic generation (SHG) we achieve significant laser power at the visible and NIR regime (figure 1; red-shaded cells of table 1). With the development of periodic poled crystal technology and the associated waveguide technology, nonlinear frequency conversion has become a powerful tool to extend the application scope of fiber lasers. For QTekLaser products, the max power of the converted laser light is constrained by the damage threshold of commercially available nonlinear crystals, which is typically several tens of watts.
