Where to Buy Tunable Lasers

The Stuttgart Instruments Alpha system is a modular, wavelength-tunable laser covering the 700 nm to 20 µm spectral range. It provides ultrafast pulses at MHz repetition rates and milliwatt- to watt-level power. Due to its excellent passive long-term stability, outstanding performance at the shot-noise limit and broad spectral range, it is ideally suited for sensitive IR applications.

The Alpha system can be configured optimum for your application. Its basic version is tunable from 1.35 µm to 4.5 µm, but can be upgraded to higher power, to the VIS (700 – 980 nm), the NIR (1.1 – 1.4 µm) and the MIR range (4.5 – 20 µm). Each module is field upgradable, and the entire system is fully automated and controlled via a user-friendly GUI.
