The 3900S CW Tunable Ti:Sapphire Laser offers up to 3.5 W TEM00 output power and is tunable from 675 to 1100 nm. It features computer-optimized easy alignment and a narrow linewidth option.

The Spectra-Physics Model 3900S is a high-performance, tunable, solid-state IR laser. It provides tunable, continuous wave (CW) output from 675 to 1100 nm in a cost-effective package. It can be pumped with either an argon ion laser or a 532 nm diode-pumped solid-state laser, producing up to 3.5 W of TEM00 output, suitable for a wide range of IR applications.

• Output Power: Up to 3.5 W TEM00
• Tuning Range: 675 to 1100 nm
• Linewidth: Standard <40 GHz, with Thin Etalon <15 GHz, with Thin/Thick Etalon <1 GHz
• Stability: Noise <1%, Power Drift <3%
• Beam Characteristics: Spatial Mode TEMoo, Polarization >100:1 Horizontal, Beam Diameter 0.95 mm, Beam Divergence <1 mrad

The typical tuning curve shows output power across different wavelengths, with specific power outputs for various optics configurations (e.g., Millennia eV 15 W, 10 W, 5 W).

The 3900S is a Class IV high-power laser, posing safety and fire hazards. Precautions are necessary to prevent exposure to direct and reflected beams, as both diffuse and specular reflections can cause severe skin or eye damage. The product is compliant with ISO 9001 standards.
