Where to Buy Wavelength-tunable Light Sources

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.

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.

Serving North America, RPMC Lasers offers a selectionwavelength-tunable lasers including the Q-TUNE family of pulsed DPSS lasers, utilizing an Optical Parametric Oscillator (OPO) to produce tunable wavelengths from 210 – 4500 nm. The advanced laser design results in a compact, user-friendly turnkey system that requires little maintenance. It integrates all laser electronics into the housing and there are no chillers or bulky power supplies needed. We also provide several tunable, DFB-like laser diodes and quantum cascade lasers (QCLs) with wavelengths ranging from 11.3 µm to 16 µm, designed for use in the detection and monitoring of critical, gaseous compounds in the industrial and nuclear industries. Standard and custom options available. Let RPMC help you find the right laser today!

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.

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, Python, 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.

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.
