Wavelength Stabilized Lasers

for Spectroscopy and Analytical

Instrumentation

All SureLock™ Wavelength Stabilized Laser Diodes and Laser Modules

incorporate the Coherent PowerLocker

VHG lter, a miniature, ultra-

narrowband Volume Holographic Grating (VHG), creating an external

cavity that “locks” the diode laser wavelength into a narrowed optical

spectrum. This increases spectral brightness and delivers stabilized

optical performance over extended temperature ranges, transforming

standard diode lasers into single-frequency or spectrum-narrowed,

instrument-quality lasers. The extremely short external cavity congura-

tion results in better mode selection and a smaller footprint than

Littrow or Littman cavity designs, while reducing the spectral bandwidth

of a typical laser by an order of magnitude.

FEATURES & BENEFITS

• Stabilized wavelength over a broad

temperature range

• Single frequency or spectrum-narrowed

operation

• Free-space and fiber-coupled options

• Ultra-compact footprints

• Laser components to turnkey modules

with temperature and current controls

• Available computer and onboard

user interfaces

APPLICATIONS

• Raman Spectroscopy

• Holography

• HeNe Replacement

• Particle Characterization

• Analytical Instrumentation

• Speckle Interferometry

• Metrology and Inspection

PRINCIPLE OF OPERATION

The PowerLocker

acts as an ultra-narrowband, wavelength-selective

lter that provides stable, controlled optical feedback into the laser.

This increases the power in the desired mode and reduces unwanted

spectral components, reducing the linewidth of multimode lasers or

forcing single mode lasers into single frequency operation.

COMPREHENSIVE PERFORMANCE

AND CHARACTERIZATION TESTING

All SureLock™ lasers are thoroughly characterized using

our proprietary automated test stations, providing detailed

information about wavelength, temperature stabilized range,

and mode hop behavior. Our unique “3D” color plots of

wavelength as a function of both temperature and current

also provide an integrated view of the performance to enable

the user to select the optimal operating point.
