TOPTICA’s TA FHG pro – Frequency quadrupled tunable diode laser

TA-FHG pro

  • High-power, tunable, single-frequency diode laser
  • Two resonant frequency doubling stages
  • Wavelengths: 190 .. 390 nm, up to 500 mW
  • New: SUV-option - unprecedented DUV power & lifetime
  • New: Digital control with AutoAlign and PowerLock

The TA-FHG pro is a tunable, diode-based laser source in the deep UV spectral range. The system consists of an external cavity diode laser, a high power semiconductor amplifier (TA), and two cascaded second harmonic generation stages (SHG pro). Alternatively, it can be equipped with a fiber amplifier (FA) or Raman fiber amplifier (RFA). It provides tunable laser radiation for spectroscopy, laser cooling, holography and interferometry.
