Where to Buy Laser Spectroscopy Equipment

The grating based HighFinesse/ Ångstrom’ spectrometers offer the capability for a very accurate simultaneous measurement of both wavelength and linewidth of laser sources. With a resolving power up to 40000 and a measurement speed up to 500 MHz, the product series covers the range from 192 nm to 11000 nm, allowing measurements of both pulsed and cw lasers. The grating based technology enables the analysis of laser sources over a large linewidth range. Connected to the PC via USB, after a simple software installation the spectrometers are ready for use.

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.

TOPTICA offers industrial and research grade lasers for spectroscopy with an ultra-broad wavelength coverage: 190 nm – 0.1 THz. TOPTICA lasers deliver narrow-linewidth emission that is tunable – in some systems up to 110 nm wide without a single mode hop.

High-end, turn-key difference frequency combs and terahertz systems complement the portfolio for the most demanding spectroscopy applications.

Sacher Lasertechnik offers various types of equipment for laser spectroscopy:

• reference gas and vapor cells including heaters
• setups for RF modulation spectroscopy and for Doppler-free saturated absorption spectroscopy

GWU offers widely tunable lasers as well as spectrometer solutions. The sophisticated optical and mechanical design of our laser sources ensure excellent performance, highest reliability and longest lifetime. Continuous, gap-free tunablity from the deep-UV to the infrared spectral range is offered for best usability. GWU's portfolio of CCD based spectrometers provides a great variety of features to fulfill nearly any requirement of versatile applications. The detection range covers the UV to near-infrared spectrum and even reaches out to the mid-infrared at 2.6 µm. Models with tiny footprint, e. g. for wavelength monitoring in OEM applications, as well as thermo-electric (TE) cooled devices with high resolution, high sensitivity and ultra-low noise for weak-light applications, such as fluorescence sensing or Raman analysis, can be offered.
