Blue-Violet Laser Diodes give up to 85mW optical output power
Photonic Products, the UK optoelectronics device manufacturer and laser diode specialist, has announced that Sanyo’s tiny blue-violet laser diodes are now available in industrial strength and power: three new 405nm laser diodes which offer 20mW, 45mW or a massive 85mW optical output power, 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 stabilise 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.
The three 405nm wavelength Sanyo laser diodes are DL-4146-101S which gives 20mW optical output power with a very low threshold current of 26mA, typical operating current of 35mA, operating voltage of 4.8V and monitoring output current of 0.2mA; DL-5146-101S that offers 45mW power with a threshold current of 35mA, typical operating current of 70mA, operating voltage of 5.2V and monitoring output current of 0.3mA, and the remarkable DL-7146-101S laser diode which gives 85mW output power with a threshold current of 45mA, typical operating current of 110mA, operating voltage of 5.4V and monitoring output current of 0.3mA.
All three laser diodes have an internal monitor photodiode, a tiny package size of 5.6mm and operate at a temperature of 0 degrees Centigrade to +75 degrees Centigrade.
