Fiber-Pigtailed Laser Diodes
Mar 2008
Ondax Inc.Request Info
MONROVIA, Calif., March 12, 2008 -- Ondax has introduced multimode fiber-pigtailed, single-mode wavelength-stabilized laser diodes that have a linewidth of less than 50 MHz.

Wavelength stabilization is achieved by optical feedback using Ondax's volume holographic grating (VHG), the PowerLocker. The PowerLocker VHG is a glass grating that diffracts a defined efficiency at a specific wavelength. The gratings increase spectral brightness of laser diodes, locking their wavelength and increasing temperature stability and yield. The PowerLocker VHG is available in wavelengths from 350 nm to 3 µm, Ondax said.

Ondax.jpgLawrence Ho, product line manager, lasers, said, "Ondax Inc. has introduced this new pigtailed laser product line to offer our customers increased flexibility in their system design. Customer response to our stabilized lasers has been consistent; these are rock-solid lasers that do not exhibit any mode hopping. Our customers are using these lasers in many applications where a true single-mode robust laser with a small footprint is essential to enable, for example, their handheld products. Furthermore, our TO-can package allows for direct drop-in replacement without any time consuming and costly redesign of existing systems and instrumentation. This is critical in today's competitive market."

The lasers are packaged in standard 5.6-mm TO cans, fiber pigtailed, and include a FC/APC connector. Standard wavelengths are 636-640 nm with greater than 4 mW output power, 654-662 nm with greater than 15 mW output power, 681-685 nm with greater than 20 mW output power, and 780.25 nm and 781-789 nm with greater than 40 mW output power. Custom wavelengths, TO-can diodes, and fiber-coupled modules are also available.

Applications for the fiber-pigtailed lasers include: Raman spectroscopy, flow cytometry, metrology, bioinstrumentation, graphic arts, analytical instrumentation, sensing, and data storage, among others. Datasheets on the diodes can be found at: The lasers can be purchased via the Ondax store online or by purchase order.
