Where to Buy Wavelength-tunable Light Sources

The Zolix tunable light source (TLS) is a pre-aligned, pre-assembled illumination system capable of emitting monochromatic light from 200 nm on. The completely plug & play system is very easily controlled by software. It is widely used in fluorescence spectroscopy.

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.

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.

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.

For the efficient generation of wavelength-tunable monochromatic light, we offer the Monochromator-H and Hyperchromator in conjunction with suitable white light sources:

• The Monochromator-H has an integrated halogen lamp, covering the range from 340 nm to 2000 nm.
• The Hyperchromator is specifically made for the laser-pumped XWS-30 light source from ISTEQ. It works from 190 nm to 2200 nm.

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.

The Stuttgart Instruments Alpha is an ultrafast and fully wavelength-tunable frequency conversion system in an ultra-compact and completely passively stable system based on revolutionary parametric oscillator design which guarantees outstanding stability, reproducibility and shot-noise limited performance.

The revolutionary design of Stuttgart Instruments Alpha, characterized by outstanding low noise and passive long-term stability, is based on the fiber-feedback optical parametric oscillator (FFOPO) technology and results in outstanding performance and high flexibility at the same time.

The Alpha covers a gap-free rapid tunable spectral range from 700 nm to 20 µm wavelengths, while maintaining high output power up to the Watt-level with femto- or picosecond pulses at several MHz pulse repetition rates. It provides multiple simultaneously tunable outputs with a selectable bandwidth from a few to 100 cm⁻¹. Shot-noise limited performance above 300 kHz, passive spectral stability (< 0.02% rms) and wavelength-independent stable beam pointing (< 30 µrad) enable excellent sensitivity. In addition, each Alpha is equipped with a user-friendly ethernet and Wi-Fi interface and a matching graphical user interface (GUI) as well as easy to access API interfaces for e.g. LabView, Phyton, C++.

Typically, the Alpha is pumped by an ultra-low-noise Primus pump laser, which provides more than 8 W average output power at 1040 nm wavelength and 450 fs pulse duration at 42 MHz repetition rate. In addition, the Alpha can be operated with other pump lasers around 1 µm wavelength and enough power.

Due to our modular platform, the Alpha can be adapted and optimized for various applications and is particularly suited for spectroscopic applications requiring a robust and reliable tunable radiation with low noise.
