Opnext visible laser diodes 633nm - 690nm
Opnext AlGalnP red (visible wavelength) laser diodes with multi quantum well (MQW) structures in the 635nm - 690nm wavelength range, with powers up to 130mW are now available in 5.6mm & 9mm packages with 'N' or 'P' or 'laser only' pin configurations.
The new Opnext HL6750MG visible laser diode is a 685nm AlGaInP laser diode with a multi-quantum well structure has a high optical output power of 50mW CW, a small package size of 5.6mm and a built-in photodiode for monitoring laser output which allows for easier control of the auto power circuit. It is ideal for use in medical and biomedical applications such as X-Ray scanners, industrial and medical sensor light sources and as a light source for various other types of optical equipment such as distance meters, barcode scanners and high resolution CTP.
Opnext has also introduced the HL6364DG, HL6365DG and HL6376DG, the first low-operating current and high optical output power red laser diodes, (640nm wavelength band, 65mW max. optical output power) which offer the World's highest output power in 640nm laser diodes for applications including industrial and medical sensors and display light sources. In order to reduce the low operating current to 1125mA, the Multi-Quantum Well (MQW) *1structure and wave-guide structure are optimized. Also, the aspect ratio*2 has been successfully improved from 3.5 to 2.1.
Another World First for Opnext is the HL6366DG, HL6367DG, HL6378DG series of 642nm visible wavelength laser diodes which offer the highest ever optical output power of 90mW (max.) in a 5.6mm package with high temperature operation of 50 degrees C with a low operating current of 155mA typ. They are ideal as light sources for laser displays.
