Ushio introduces new single-mode 670 nm red laser diodes

Ushio, Inc. has begun the mass production of HL67191MG and HL67192MG, offering two new red laser diodes (LDs) for operation at the 670 nm wavelength. Providing an optical output power of 15 mW (CW) and 30 mW (pulsed), these single-mode LDs deliver high-temperature performance (up to 70°C) within a compact φ5.6 mm can package. Both LDs achieve a low operating current of 30 mA at 25°C (15 mW in CW operation) and feature built-in monitoring photodiodes.

Despite maintaining Ushio’s trademark high-quality, these new red laser diodes offer a number of improvements over some existing models. In keeping with Ushio’s habit of providing customisation options, engineers gain more freedom to fit the LDs into their preferred electrical circuit structure, with the added possibility to feature an extra pin-out for the new models.

Ushio’s previously existing 670 nm laser diodes (HL6714G; HL6748MG; HL6756MG) laser diode are able to withstand ambient temperatures of up to 60°C. Now, with the release of the two new models, an additional 10°C margin brings a new level of durability to Ushio’s laser line-up. Not only does this allow the lasers to remain fully operational in hotter environments, but they remain unaffected in situations which would previously contribute to the premature failure of the LDs. This feature increases the suitability of these lasers to be implemented into devices which do not feature an active cooling element.

These qualities combine to result in a pair of high-reliability, cost-efficient emitters which are ideal for battery-powered sensing and precise measurement equipment.
