3900S

CW TUNABLE TI:SAPPHIRE LASER

  • Up to 3.5 W TEM00 output for high-power applications
  • Tunable from 675 to 1100 nm
  • Computer-optimized Z-fold cavity for maximum power and ease of alignment
  • Etalon option available for narrow linewidth applications

3900S CW Tunable Ti:Sapphire Laser

The Spectra-Physics Model 3900S is a high-performance, tunable, solid state IR laser. It delivers tunable, CW output from 675 to 1100 nm in a low-cost package. Pumped with either an argon ion laser or 532 nm diode-pumped solid state laser, the Model 3900S solid state Ti:Sapphire laser produces up to 3.5 W of TEM00 output for the broadest range of IR applications.
