TA-SHG pro



  • Resonant frequency doubling stage
  • Wavelengths: 330 .. 780 nm, linewidth < 500 kHz
  • AutoAlign and FiberMon options
  • PowerLock output power stabilization
  • With digital control DLC pro: Less drift & linewidth

The TA-SHG pro system, part of the UV / RGB solutions, comprises a tunable diode laser, a high power semiconductor (TA) and an integrated frequency doubling stage (SHG pro). Alternatively, it is available with a fiber (FA) or Raman fiber (RFA) amplifier. The SHG stage is a folded ring cavity in bow-tie configuration with excellent thermal and mechanical stability.

The system now includes fully-automated push-button coupling optimization into the TA chip, the SHG cavity and the output fiber, as well as output power stabilization. It provides tunable laser radiation for spectroscopy, laser cooling, optical data storage, holography and interferometry.

The rack-mounted version of TA-SHG pro for integration into T-RACK is available as MSHG pro.
