Where to Buy Nonlinear Frequency Conversion Equipment

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.

XUUS upconverts ultrafast laser pulses into the Extreme UV (EUV or XUV) or soft X-ray regions of the spectrum. Employing high harmonic generation processes, the output beam inherits the coherent properties of a driving laser such as the KMLabs RAEA with wavelengths that can be tuned from  10 nm to 47 nm. Moreover, customized systems can generate coherent beams with wavelengths as short as 6.5 nm. XUUS employs KMLabs' patented hollow waveguide for the high harmonic upconversion process.

The XUUS hollow-core fiber, or waveguide, architecture enables harmonics generated by the system to be distinguished from other HHG methods, guaranteeing your harmonics originate from the same point in space every time, minimizing any pointing drift. This optimizes repeatability for your experiments. Additionally, the use of a fiber rather than typical gas jet or semi-infinite gas cell target geometries provides superior pressure tunability for phase-matched HHG.

If frequency conversion is needed, we offer second harmonic modules and third harmonic modules for some of our most popular lasers. For our Koheras BOOSTIK narrow linewidth laser, we offer the Koheras HARMONIK module that converts 1550 nm or 1050 nm to 780 nm. For our Origami XP high power ultrafast laser, we offer SHG and THG modules that convert 1030 nm to 515 nm and 343 nm, respectively.

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.

GLOphotonics is offering a unique frequency conversion solution based on hollow core photonic crystal fiber: the CombLas technology. This platform enables the generation of light from the UV up to the mid-IR with very high power spectral density. The Comblas can generate a comb of discrete lines or can be tuned to generate a single specific wavelength.

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.
