Volume Holographic Gratings,  Wavelength-Stabilized Lasers &
THz-Raman® Spectroscopy Systems

Ondax, Inc. is the market leader in the design, manufacture and marketing of high-performance holographic optical filters, wavelength-stabilized laser sources, and high-performance, THz-Raman® Low-frequency (Low-wavenumber) Raman Spectroscopy Systems for a wide range of industrial, scientific, defense and consumer applications. Our core technology is state-of-the-art Volume Holographic Gratings (or VHGs, also known as Volume Bragg Gratings or VBGs) – which are specialized optical filters fabricated from proprietary photosensitive glass.

VHGs are exceptionally versatile optical components that provide wavelength stabilization, spectral and temporal control for lasers/laser-based systems, and dramatically enhance the optical performance and resolution of spectroscopy systems. Our products enable our customers to make their lasers and optical systems, smaller, more portable, more efficient, less expensive and more environmentally stable and robust.

Volume Holographics Gratings

PowerLocker® wavelength stabilization gratings are designed to reflect a specified wavelength at a given reflectivity, locking the emission wavelength, increasing spectral brightness, and improving environmental performance of laser diodes.

Thz Raman Low Frequency

Ondax’s patented THz-Raman® Systems enable fast, clear capture of Raman spectra in the Ultra-Low-Frequency/THz regime (10 cm-1 to 200 cm-1, or 300 GHz to 6 THz), using only a standard single-stage spectrometer.

Wavelength Stabilized Lasers

All SureLock™ Wavelength Stabilized Laser Diodes and Laser Modules incorporate the Ondax PowerLocker® VHG filter to provide single-frequency or narrowed linewidth spectral performance, stabilized temperature operating characteristics …

SureBlock™ Ultra-Narrowband Notch Filters

Choose from a suite of high-performance, ultra-narrowband filters and assemblies specifically designed for low-frequency THz-Raman® applications.

PicoPulse Pulse Stretcher/Compressor Filters

Ondax’s PicoPulse™ pulse stretcher/compressor filters enable high peak power in femtosecond pulsed laser systems, with a distortion free round output beam. Free space operation in PicoPulse™ filters allows larger input beams to be used with many orders of magnitude higher power than chirped Fiber Bragg Gratings (FBGs).

Applications

Volume Holographic Gratings (VHGs) are specialized optical filters that are fabricated from proprietary photosensitive glass, and are used in a variety of photonics applications. Whether it be for stabilizing the wavelength of diode lasers, providing spectral or temporal control for lasers and laser-based systems, or enhancing optical performance and resolution of spectroscopy systems, Ondax VHGs and VHG-based products enable our customers to make their lasers and optical systems smaller, more portable, more efficient, more affordable, and more environmentally stable and robust.
