Stuttgart Instruments

Stuttgart Instruments is specializing in the field of widely tunable and fully automated high-performance infrared laser sources. The systems can cover a spectral range from 700 nm to 20 µm wavelengths, while maintaining high output power at Milliwatt to Watt-levels. Femto- to picosecond pulses at several MHz pulse repetition rates can be provided and the lasers are characterized by outstanding low noise and passive long-term stability.

Stuttgart Instruments is a spin-off company of University of Stuttgart providing versatile and robust laser sources for all kinds of spectroscopic applications, such as vibrational IR spectroscopy, coherent Raman spectroscopy, multiphoton microscopy and many more. At the end of 2017, Stuttgart Instruments was founded based on renowned research work at the University of Stuttgart.

Multiple systems are already in use at universities and research facilities around the world and enabled numerous scientific publications.

Alpha:

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.
