TA / FA SHG pro – Frequency Doubled, High Power Tunable Diode Laser

TA/ FA SHG pro

  • UV, blue, green, yellow wavelengths: 320 .. 590 nm
  • High power: Up to 2 W
  • Single-frequency operation, linewidth < 500 kHz (typ.)
  • Seed: Tunable, grating stabilized diode laser
  • Amplifier: Semiconductor or fiber amplifier
  • SHG: Resonant frequency doubling stage
  • Probe beam output of fundamental laser
  • Mode matching and beam shaping optics integrated
  • Increased amplitude stability with "noise eater" option
 
The TA / FA SHG pro system comprises a tunable, grating-stabilized diode laser, a high power semiconductor (TA) or fiber (FA) amplifier, and an integrated frequency doubling stage (SHG pro). The SHG stage is a folded ring cavity in bow-tie configuration with excellent thermal and mechanical stability. The system provides tunable laser radiation for spectroscopy, laser cooling, optical data storage, holography and interferometry.

TA / FA SHG pro – Frequency Quadrupled Tunable Diode Laser

TA/ FA SHG pro

  • Tunable “deep UV” laser radiation: 205 .. 295 nm
  • Up to 100 mW output power
  • Transversal single-mode beam, single-frequency output
  • Linewidth 1 MHz typ., can be narrowed by active frequency locking
  • Seed: Tunable, grating stabilized diode laser
  • Amplifier: Semiconductor or fiber amplifier
  • Two cascaded SHG pro doubling stages
  • Designed for ultra high resolution spectroscopy (e.g. Hg, H, Mg, Al)

The TA / FA 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 (TA) or fiber (FA) amplifier, and two cascaded second harmonic generation stages (SHG pro). The TA / FA FHG pro systems cover wavelengths from 200 nm to 295 nm – with best possible beam quality, long coherence length, true cw operation, and in a reliable setup.
