Ondax's PowerLocker® wavelength stabilization gratings are volume

nnnn

holographic gratings (VHGs) that "lock" a laser diode's emission

nnnn

wavelength into a narrowed optical spectrum. This increases the

nnnn

spectral brightness and delivers highly stablized optical performance

nnnn

over extended temperature ranges. PowerLockers® typically reduce

nnnn

the spectral output of a laser by an order of magnitude. The short

nnnn

external cavity configurations enabled by the PowerLocker® design

nnnn

deliver better mode selection than systems based on Littrow or

nnnn

Littman cavities, at a fraction of the size and cost.

nnnn

All Ondax VHGs are bulk "solid-state" diffractive holographic filters,

nnnn

which unlike thin films or gels, can deliver ultra-stable, degradation-

nnnn

free performance for the lifetime of the filter. Capable of very tight

nnnn

wavelength, efficiency, bandwidth, and diffraction angle control,

nnnn

Ondax VHGs can be precisely and reproducibly engineered to meet

nnnn

even the most demanding spectral and temporal specifications.

nnnn

Proprietary materials, manufacturing and test processes ensure

nnnn

consistent, repeatable performance from every single filter, every

nnnn

time, guaranteed.
