New Laser Diodes in industry:
OPI Photonics has just launched its new line of blue laser diodes, BrighteX Blue. The products currently available in the line offer an output power of 35W delivered through either a 100μm or 200μm fibre; both offer 95 per cent power within a 0.15 numerical aperture. The next releases in the line will include a 100W version on a 200μm fibre, and a 10W version on a 50μm fibre.
These multi-emitter modules offer flexible, reliable and affordable solutions for marking, material processing, medical and projection applications.
Laser 2015: new diodes and drivers aid push towards point-of-care photoacoustics.
Mitsubishi Electric unveils 25G DFB laser with 10mW output at 85°C for 100G fiber-optic systems. Tokyo-based Mitsubishi Electric Corp is unveiling a distributed feedback (DFB) laser diode for 25Gbps fiber-optic communications in 100Gbps systems operating over a wide range of temperatures from -20°C to 85°C. Four DFB laser diodes can be mounted on 100Gbps high-speed communication transceivers in order to achieve lower power consumption and enhanced communication performance for increased efficiency in data centers. The new DFB laser diode should also help to simplify the requirements for transceiver design, says the firm.
Osram SPL BF98-40-5 60W laser bar reduces system costs for fiber-coupled diode lasers.?
It has a wavelength of 976 nm and high brilliance. The laser achieves a brilliance of 3 W/mm and a 1-mrad divergence angle at an optical output of 44 W. Osram SPL BF98-40-5 offers electro-optical efficiency of 65 percent, reducing the level of cooling needed for the laser diode,improving the efficiency of the entire system.
Mitsubishi 638nm red laser diode for Projectors offering Industry's Leading Output.?
Mitsubishi has developed a 638nm red laser diode with output power of 1.8 W at continuous-wave operation, clicking the world’s highest level among the 638nm LDs. The 1800mW 638nm red laser ld can be used as a light source for projectors. The luminosity exceeds 220 lumens due to lasing at short wavelength.
Furthermore, it has industry leading electrical conversion efficiency of 38% at 1.8 W at 25 degrees Celsius, resulting in reduction of power consumption. It offers excellent heat dissipation due to use of large TO-can package with diameter of 9.0 mm.
The laser diodes are the key part of any laser system. They have different shapes and size.
Nichia is the most famous brand for the laser diodes.

Distributed feedback laser is a type of laser diode, quantum cascade laser or optical fibre laser. Distributed feedback laser is named DFB laser. The active region of the device is periodically structured as a diffraction grating. The structure builds a one-dimensional interference grating (Bragg scattering). The grating provides optical feedback for the laser.?DFB laser diodes do not use two discrete mirrors to form the optical cavity.?
