The answer for [Owen Schafer] was to build it with parts he had lying around and a few strategic purchases. While he was initially planning on using a diode laser, doing anything more than ...

Fortunately, he had some random components sitting in his parts bin, and he was able to build his own line laser without spending a ton of money. His tutorial actually covers two different methods ...

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 ...

Spectacular increase in brightness and decrease in pulse duration of X-ray beams are now foreseen owing to the progress made in laser–plasma interactions. At the frontier between plasmas and ...

Most theoretical studies on "beam riders" for interstellar travel have focused on laser beams, which are composed of particles of light called photons. Notable examples include laser-powered ...
