Low-threshold yellow laser diodes

Yellow laser diodes with low thesholds have been produced by Jijun Feng (University of Shanghai for Science and Technology, China) and Ryoichi Akimoto (National Institute of Advanced Industrial Science and Technology (AIST), Japan) based on beryllium zinc cadmium selenide (BeZnCdSe) single quantum well (SQW) light-emitting active regions [Appl. Phys. Express, vol9, p012101, 2016].

The researchers see important potential biomedical applications for yellow (560-590nm) lasers such as flow cytometry and treatment of ocular disorders. Feng and Akimoto recently reported [green and green-yellow laser diodes based on BeZnCdSe technology
