The future of lighting will be laser, said Nobel Laureate in Physics Shuji Nakamura and fellow colleague Professor Steven DenBaars of University of California, Santa Barbara UCSB at an exclusive forum hosted by Taiwanese leading chip LED manufacturer Epistar on Wednesday at the company headquarters in Hsinchu, Taiwan.
Laser diodes will become a next major lighting field, said Nakamura and DenBaars. Lasers are similar to blue LEDs when it comes to the energy transition level at E3, which is about 70% compared to LEDs 75%, said Nakamura. Finding a good omni-conduct on sapphire will be important in developing laser technology, but making stable lasers will be the greatest challenge, he added. Nakamura even suggested collaborating with Epistar on certain research.
