Phase-locking has improved the beam quality and spectral purity of a 3.3THz (~91µm) quantum cascade laser (QCL), achieving single-mode operation at 2W output. High radiative efficiency is one of the ...
Osram is aiming at rock and pop gig lighting with a bright blue laser for spotlights and vector projectors. “Lasers combine an outstanding form factor with excellent beam quality, making them ...
