Buying Nonlinear Frequency Conversion Equipment

The Nano4th is an ultra-compact device that converts your femtosecond low-energy IR laser pulses (nJ-range) into 2^nd and 4^th harmonics with best-in-class conversion efficiency. Its industrial-grade design makes it a robust and reliable solution that will extend the capabilities of your laser. The design is easily adaptable to higher pulse energies, up to the microjoule or millijoule level.

NLIR's SPEKTRUM Wavelength Converter efficiently converts wavelengths from 1.9 – 5.3 µm in the mid-infrared to 682 – 886 nm in the visible/near-infrared (VIS/NIR). This conversion is simultaneous and does not require time lag or scanning elements. The output is compatible with standard fiber-coupled grating spectrometers or silicon-based sensors.

NLIR's TUNE Wavelength Converter is optimized for high conversion efficiency within a narrow bandwidth, ideal for sensitive mid-infrared light measurements. It operates over a tunable range from 2.7 – 4.3 µm, with the converted light shifted to 763 – 853 nm, suitable for any fiber-coupled detector operating in these near-infrared wavelengths.

The TUNE Wavelength Converter is particularly effective for detecting narrowband signals, whether weak or rapidly varying. It supports measurements with time-gated PMT, SPAD detectors, APDs, and high-speed PIN photodiodes.

Now you can read mid-infrared data with your VIS/NIR spectrometer/detector.

The Hollow-Core PCF and Photonic MicroCell Company

Hollow-core fiber technology has enabled gas–light interactions with an unprecedented efficiency. Our frequency conversion and laser products take direct advantage of this feature, offering ‘multiple lasers in a single device’ in the form of CombLas – a highly versatile and stable Raman laser source which spans the UV-VIS spectral range. Combined with the device’s compact footprint, we obtain a highly-potent light source which perfectly suits the fields of gas spectroscopy and bio-imaging.
