Visible laser/amplifier

The SDL-7350 monolithic optical power amplifier emits u¥to 500 mW of 670- to 690-nm light in a single spatial mode, nearly diffraction-limited beam. The amplifier is fabricated with a distributed-Bragg-reflector oscillator and flared amplifier on a chip. It uses InGaAl¥materials to provide visible output.

A still from a video (link below) shows polymer microdisks being transferred to glass via laser catapulting. Laser catapulting can also be used to fabricate an array of microlenses directly on top of a photodetector array (inset), useful for directing more light onto the most sensitive parts of the detector.

For a microcrystalline SiC thin-film thermal emitter in a cavity-coupled setup (a), a platinum heater ring (b) heats the suspended thermal emitter structure while minimizing conductive losses into the surrounding substrate. The suspended region stays hot while the temperature shifts to blue (cold) in the nonsuspended region of the substrate (c). (Image credit: Columbia University)
