Novel Approach toward High Brightness Mid-Infrared Lasers

Semiconductor lasers covering mid-infrared wavelength range have been receiving extensive attentions in recent years. Many primary challenges, however, have been impeding their development progress for many years. Brightness of those developed versions, for example, is still not high enough for practical uses. Brightness depends mainly on the output intensity and beam profile. Wavelength coverage, which is required to cover full mid-infrared range, is another concern. To widen this wavelength coverage, new material system is thus highly needed. In this program, Lutronics uses an innovative structural design and a new material system to reach the goal with effectiveness. The program will be fully grounded with Lutronics's advanced MBE facilities and strong expertise in semiconductor laser development.
