TOPTICA’s DL SHG pro – frequency-doubled tunable diode laser.

DL-SHG pro

  • Tunable, single-frequency diode laser
  • Resonant frequency doubling stage
  • Wavelengths: 316 .. 680 nm, linewidth < 500 kHz
  • New: AutoAlign, PowerLock and FiberMon options
  • New: Digital remote control DLC pro

  

The grating stabilized diode laser SHG pro is a medium power solution, for applications such as spectroscopy of atoms, ions and molecules, laser cooling and interferometry. Designed in TOPTICA’s proprietary pro technology, it combines best performance and ease-of-use – at moderate initial and operating costs. The system now includes fully-automated push-button coupling optimization into the SHG cavity and the output fiber. The package comprises a solid laser head and a DLC pro control rack. It can be upgraded to a TA SHG pro, if an appropriate amplifier source is available.
