Laser for High Power RGB White Light Source
Photonic Products is the authorised distributor of what is said to be World's first 642nm, 150mW, single longitudinal mode semiconductor laser diode with TE mode oscillation; the Opnext HL6385DG. This laser diode from Opnext offers the highest optical output power on the market at a visible lasing wavelength of 642nm. Opnext's technology breakthrough was achieved with a new development process, a new waveguide structure and optimised structural p...
Wavelength Stabilised Laser Diodes
Photonic Products, the UK opto-electronics device manufacturer and laser diode specialist, has been appointed by Ondax as authorised European distributor for its range of wavelength stabilised laser diodes which are low cost, miniature lasers in a standard TO package. Stabilisation is achieved using the Ondax Volume Holographic Grating (VHG) PowerLocker(tm). The PowerLocker(tm) increases the spectral brightness of laser diodes, ensuring a precise...
640nm laser diodes combine high visibility with low operating
Photonic Products has introduced two new red laser diodes from Opnext Inc. which combine a low operating current with a high optical output power. The HL6362MG/HL6363MG laser diodes (640nm wavelength band, 45mW maximum optical output power) are ideal for use in medical scanners, measurement equipment and next-generation display applications.
Stable 405nm, 35mW blue-violet laser diode monitors itself
Photonic Products has announced a lead-free, blue-violet wavelength (405nm) laser diode from Sanyo. The Sanyo DL-5146-152 405nm, 35mW CW (50mW pulsed) laser diode incorporates an internal monitor photodiode which can be utilised to accurately stabilise and control the optical output power.
DC/DC Controller Supports Input Voltage Ranges from 4.5 V to 20 V
Texas Instruments has introduced a flexible, synchronous buck controller that simplifies power management design of LCD TVs and IP set-top boxes that use digital signal processors (DSPs) and FPGAs. TI's new TPS40195 high-performance controller provides several features to enhance the power performance of a 4.5-V to 20-V system. For instance, the device uses the input voltage available for power conversion as its bias supply, eliminating the need ...
ORing Controllers Protect Server and Telecom Power Systems from Transient Events
Texas Instruments has introduced a family of ORing power controllers with advanced features and high performance that improves power distribution in 12-V blade servers, N+1 telecom systems and redundant low-voltage processor power supplies. The integrated circuits provide a high-efficiency replacement for ORing diodes, and offer intelligent monitoring and control of power supplies to prevent bus transient events from causing board-damaging faults...
Closed-loop, digital-input class-D amplifier is a first says TI
Texas Instruments has introduced the industry’s first digital-input, 20W stereo Class-D speaker amplifier with closed loop feedback. Closed loop architectures produce a richer, more accurate sound and lower system cost by relaxing power supply performance requirements. Highly flexible output configurations along with intuitive support tools ease design and speed time to market for manufacturers of HDTVs, including LCD, plasma and DLP TVs, a...
