HATFIELD BROAD OAK, England, Jan. 15, 2008 -- Photonic Products, an authorized distributor, announced that Sanyo's blue-violet laser diodes are now available in industrial strength and power: Three new 405-nm laser diodes that offer 20 mW, 45 mW or 85 mW of optical output power, which it said is the highest power available in a single-mode laser diode with an internal monitor photodiode.

This internal monitor photodiode, which can be used to accurately stabilize and control the optical output power -- plus their stable beam structure, lower noise and lower current consumption --enables these new Sanyo blue-violet laser diodes to offer the performance required for critically demanding industrial and medical applications such as biomedical instrumentation, medical imaging, fluorescence sensing, high-resolution printing, advanced DVD and industrial alignment, according to Photonic Products, a StockerYale company.

PhotonicProductsLaserDiodes.jpgThe three 405-nm wavelength Sanyo laser diodes are: DL-4146-101S, which gives 20-mW of optical output power with a very low threshold current of 26 mA, typical operating current of 35 mA, operating voltage of 4.8 V and monitoring output current of 0.2 mA; DL-5146-101S, offering 45-mW of power with a threshold current of 35 mA, typical operating current of 70 mA, operating voltage of 5.2 V and monitoring output current of 0.3 mA; and the DL-7146-101S laser diode, which gives 85 mW of output power with a threshold current of 45 mA, typical operating current of 110 mA, operating voltage of 5.4 V and monitoring output current of 0.3 mA.

All three laser diodes have an internal monitor photodiode, a tiny package size of 5.6 mm and operate at a temperature of 0 to 75 °C.

A two-electrode device with an anode and a cathode that passes current in only one direction. It may be designed as an electron tube or as a semiconductor device.
The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
