Where to Buy Nonlinear Frequency Conversion Equipment

Our U2050 2–5 µm fiber to fiber wavelength conversion module converts mid-infrared 2–5 µm light to 695–877 nm light enabling the mid-infrared light to be measured with low noise near-visible detector technology.

Covesion provides off-the-shelf MgO:PPLN crystals and waveguides, which are available for SHG, SFG, DFG, and OPO interactions. MgO:PPLN supports a wide range of applications such as: quantum computing; mid-infrared generation; atom cooling; terahertz generation and biomedical imaging. Covesion also manufactures a range of ovens and a temperature controller for precision thermal management.

We offer advice on all aspects of nonlinear frequency conversion, e.g. the design of frequency conversion devices, choice of nonlinear materials, simulation of nonlinear conversion. Also: specialized in-house training courses, tailored to your needs.

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.

APE offers well engineered devices for nonlinear frequency conversion of picosecond and femtosecond pulses, including:

• frequency doubling
• frequency tripling
• frequency quadrupling
• difference frequency generation

Also, we offer optical parametric oscillators and amplifiers. The accessible wavelength range spans from 190 nm up to 15 µm, with femtosecond or picosecond pulse durations.

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.

TOPTICA provides tunable continuous-wave laser systems including nonlinear frequency conversion for accessing the wavelength range from 190 nm to 4000 nm. The conversion processes are second-harmonic generation and optical parametric generation.

Shalom EO offers a vast variety of nonlinear crystals: BBO, KDP and KD^*P, LBO, KTP, HGTR KTP, KTA, BIBO, LiIO₃, LiNbO₃, MgO:LiNbO₃, RTP, ultra-thin BBO, LBO crystals and infrared nonlinear crystals ZnGeP₂ (ZGP).

Our products are excellent for applications ranging from frequency conversion to short-pulse generation. They are used for harmonic generation (SHG, THG, 4HG, 5HG), sum and difference frequency generation (SFG, DFG), for optical parametric oscillators (OPOs) and optical parametric amplifiers (OPAs). Note that for all the products listed above, off-the-shelf and customized products are optional to our customers.

Radiantis offers second harmonic generators for MHz repetition-rate femtosecond and picosecond Ti:sapphire oscillators with conversion of efficiencies of 50%. The company also provides femtosecond SHG devices to double the 990 – 1550 nm range into the 495 – 775 nm range. Products are fully automated. Customised frequency doublers for other spectral ranges can also be developed.

EKSMA Optics offers a complete portfolio of nonlinear optical crystals: BBO, LBO, KTP, KDP, DKDP, LiIO₃, LiNbO₃, MgO:LiNbO₃, AGS, AGSe, ZGP, GaSe, CdSe from stock or manufactured according to customers specifications or for specific applications.
