Where to Buy Wavelength-tunable Light Sources

CNI offers various wavelength-tunable lasers: diode lasers (with wavelengths between 403 nm and 1074 nm), tunable DPSS wavelength-tunable lasers including tunable Ti:sapphire lasers, and tunable infrared 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.

Our tunable fiber laser covers the C-band and can address up to 89 different ITU-T standard wavelengths (with 50 GHz separation). It contains a dual Fabry–Pérot cavity tuning etalon and a high gain chip, featuring high output optical power, narrow linewidth and high wavelength accuracy. It is equipped with a dedicated drive control circuit, high-definition color LCD screen, and optional control keyboard and PC software.

All Radiantis lasers are broadly tunable lasers, specially designed for the scientific community. Femtosecond and picosecond pulses as well as continuous-wave (CW) temporal regimes are offered with automatic tuning across the UV, visible and IR.

Alpes Lasers designs and manufactures single-mode mid-IR lasers with wavelength tuning over more than 10 cm⁻¹. Broad-gain lasers with wide tuning in an external cavity are also offered.
