Researchers have demonstrated a record-high laser pulse intensity of over 1023 W/cm2 using the petawatt laser at the Center for Relativistic Laser Science (CoReLS), Institute for Basic Science in the Republic of Korea. It took more than a decade to reach this laser intensity, which is ten times...

A laser bong. Why didn't I think of that? https://mashable.com/review/hitoki-trident-laser-bong-review/

Though burning stuff with a laser is astonishing as watching paint dry, I must say this certainly surpasses paint drying. Also, what really is impressive is the work that went into using a Cassegrain telescope as a beam expander...

Brainiac reviews the Sanwu Tracer 20W power meter and the Lasertack LR2 Spectrometer using various lasers he owns.

Aqwest proposes to develop a novel, compact and rugged high-peak power blue laser in the 0.45-0.49 m range. The innovative blue laser is based on a frequency-quadrupling of 1.9-μm laser output from ceramic Tm:Lu2O3, a novel high-performance solid-state laser (SSL) material that is new becoming...

Even though this is not a laser this is what my next laser will do. This vid was shot at dusk using tracers bullets in rapid fire giving the effect of a laser beam.
