Laser diodes promise stable performance

UK-based optoelectronic device manufacturer and laser diode specialist Photonic Products has been appointed by Ondax as the authorised European distributor for its range of wavelength stabilised laser diodes which are low cost, miniature lasers in a standard TO package.

"We are delighted to supplement our current range of high performance laser diodes from Sanyo, Sony and Opnext with these specialised PowerLocker diodes from Ondax".

"We have many customers who will benefit from the stability of these devices", says Tony Wright, Director of Sales for Photonic Products.

Stabilisation is achieved using the Ondax volume holographic grating (VHG) PowerLocker.

The PowerLocker increases the spectral brightness of laser diodes, ensuring a precise centre wavelength over the locked region and improving temperature stability and yield, which enhances performance and enables many applications including storage, metrology, bio-instrumentation, analytical instrumentation, sensing, flow cytometry and graphic arts.

Ondax's PowerLocker is ideal for increasing the spectral brightness of laser diodes and locking their emission wavelength.

The short external cavity enabled by the PowerLocker provides better mode selection than systems based on Littrow and Littman cavities.

The stabilised laser has a single-mode, narrow linewidth of less than 50MHz and a very low temperature dependence of less then 0.03nm/C, compact size (5.6 and 9mm standard TO package) and is wavelength locked to better than +/-1nm.

The laser is available in standard wavelengths of; 640, 658, 685 and 785nm.

Custom wavelengths are available on request.
