Visible Lasers As the quest to integrate visible laser sources on-chip spreads through the integrated photonics sector, applications in numerous technology areas appear poised to benefit. One -- quantum, and especially quantum devices -- shows particular promise due to the range of related applications that visible sources already enable. From quantum computing to atomic clocking/precision timekeeping, to simulation, cryptography, and advanced sensing, this article focuses on present state of the link between a discernible trend in laser technology and applications in one highly coveted technology area. The article further aims to establish the nature of the relationship between integrated VIS sources and quantum applications, to determine how advances on one side of the equation are enabling -- or hindering -- growth to the other.

This article focuses on raster scanning – a technique in which the beam is deflected horizontally back and forth very quickly, and vertically up-and-down much more slowly, thus allowing the laser to cover a rectangular area. Raster scanning is used in applications such as 3D printing, and biomedical applications such as confocal microscopy and OCT. Though galvos have been used to produce raster images for nearly 50 years, simple motion profiles have been used in most instances. While these profiles/waveforms, such as triangle-wave and sawtooth-wave motions, are easy to understand, they are not optimal for galvo scanners, since the rate-of-change is too high at the turn-around point, and also because these simple waveforms may excite resonances in the rotor/mirror system, which may lead to image distortion. This article describes a set of superior motion profiles to be used as an alternative to triangle-wave and sawtooth waveforms, involving the use of so-called cycloid motions. With easy implementation, predictable results, and the ability to avoid exciting resonances of the galvo’s rotor/mirror system, cycloid motions offer numerous advantage to end users.
