The Berkeley Lab Laser Accelerator (BELLA) is a laser built by the Thales Group and owned and operated by the Lawrence Berkeley National Laboratory. [ 1 ] [ 2 ] On 20 July 2012, BELLA fired a 40 femtosecond laser pulse , establishing a world record for most powerful laser.
The Hercules 500, made by Laserglow, held the world record for the world's most powerful handheld laser in 2012, [9] and appeared in the Guinness Book of World Records in 2009. The laser was tested three times in five-minute durations using two separate laser power meters, and created an output 1W peak and 940 mW (+/- 20 mW) average power.
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
The laser may be powerful enough to produce matter and antimatter directly from a vacuum [2] (the Schwinger effect). Upon completion, the laser will be the most powerful on Earth, with an instantaneous power 10,000 times the power of all the world's electrical grids combined, and a trillion trillion times more intense than sunlight , albeit ...
Most types of laser are an inherently pure source of light; they emit near-monochromatic light with a very well defined range of wavelengths.By careful design of the laser components, the purity of the laser light (measured as the "linewidth") can be improved more than the purity of any other light source.
Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
