- Ondax Nabs NSF Grant to Develop Tunable Lasers
MONROVIA, Calif., May 13, 2010 — Ondax Inc. announced Monday that it received a $500,000 Phase II award from the National Science Foundation (NSF) to continue development of a novel miniature external cavity tunable single-frequency laser.
The grant follows an earlier demonstration of a self-aligned, nondispersive, tunable single-frequency laser that incorporates a multiline volume holographic grating (VHG) element. The second phase will help the company to extend the tuning range and develop mode-hop-free fine wavelength tuning.
With continued involvement in Phase II development work, Dr. John L. (Jan) Hall, a pioneer in single-frequency lasers and precision spectroscopy, for which he was awarded the Nobel Prize in 2005, contributed technical guidance in the first phase of the program. Hall is enthusiastic about the potential of the technology for new space-based high-precision spectroscopy applications.
The company manufactures high-performance VHG filters and wavelength-stabilized laser sources for a range of applications, including Raman spectroscopy, biomedical and analytical instrumentation, environmental sensing, metrology and scientific research.

- A framework or latticework having an even arrangement of rods, or any other long narrow objects with interstices between them, used to disperse light or other radiation by interference between wave trains from the interstices. The ability of a grating to separate wavelengths (chromatic resolving power) is expressed as being equal to the number of lines in the grating.
- The optical recording of the object wave formed by the resulting interference pattern of two mutually coherent component light beams. In the holographic process, a coherent beam first is split into two component beams, one of which irradiates the object, the second of which irradiates a recording medium. The diffraction or scattering of the first wave by the object forms the object wave that proceeds to and interferes with the second coherent beam, or reference wave at the medium. The resulting...

- raman spectroscopy
- That branch of spectroscopy concerned with Raman spectra and used to provide a means of studying pure rotational, pure vibrational and rotation-vibration energy changes in the ground level of molecules. Raman spectroscopy is dependent on the collision of incident light quanta with the molecule, inducing the molecule to undergo the change.
- tunable laser
- Any form of laser; e.g., a dye laser, having an output that can be adjusted over a wide range of wavelengths. Normally the range is about 70 nm wide.
