3900S CW Tunable Ti:Sapphire Lasers
Overview
The 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 3900S solid state Ti:Sapphire laser produces up to 3.5 W of TEM00 output for the broadest range of IR applications.
- 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
