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.

Tune your wavelength

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.

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.

Shalom EO offers a vast selection of nonlinear crystals, including 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 nonlinear crystals are excellent for applications ranging from frequency conversion to short-pulse generation. The NLO crystals offer reliable performance for harmonic generation (SHG, THG, 4HG, 5HG), sum and difference frequency generation (SFG, DFG), for optical parametric oscillators (OPOs) and optical parametric amplifiers (OPAs). Off-the-shelf and customized crystals are optional to our customers. Miscellaneous coating options including uncoated, AR, HR, HT, PR coatings, and custom coatings can be tailored. All the crystals will undergo rigorous inspection before dispatch.

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.

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.
