About |
Ondax, Inc. has been manufacturing commercial VHG filters since 2001. VHGs improve laser diode performance by increasing spectral brightness, locking emission wavelength and increasing yield. In ultra-fast lasers, chirped VHGs reduce the form factor of conventional pulse compressors by two orders of magnitude while providing higher laser power. Ondax also manufactures single frequency VHG-stabilized laser diodes at wavelengths from 403nm to 860 nm for applications in Raman spectroscopy, flow cytometry, biomedical instrumentation, semiconductor material testing, and scientific research.
