s31523 writes "We all remember the scene from the movie Real Genius where the nerdy guys get a laser to fire which burns a hole through everything for miles. The Lawrence Livermore National Laboratory in California has announced they have a Solid State Heat Capacity Laser (SSHCL) that averages 67kW working in their lab. Developed for the military, Dr. Yamamoto claims this to be a record and is quoted as saying, "I know of no other solid state laser that has achieved 67kW of average output power". The potential uses for this bad boy go well beyond turning a professor's house into Jiffy Pop. Here is what a 40w laser can do, now imagine 67000 watts. Although many lasers have peaked at higher capacities, getting the average sustained power to remain high seems to be the tricky part."
