It rarely deviates from red and green colors, perhaps blue ... which is common for continuous laser beams. In mode-locking, the amplitude (the distance between the crest and trough of a waveform ...

Scientists in Florence have built a device that allows them to study quantum and classical physics side by side. Using ...

Knowledge of a laser beam's shape and output-power distribution is critical for optimizing laser performance. Neil Savage summarizes the latest beam-profiling products on the market. People using ...

The lasers build character animations as well as shapes and vortexes with different colors. There’s even a hazer that pumps in smoke. "What’s really cool is if we project a laser beam as a ...
