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.
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). Most of the data comes from Weber's book Handbook of laser wavelengths, [1] with newer data in particular for the semiconductor lasers.
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.
The laser pointer ban only applies to hand-held battery-powered laser devices and not laser modules. [53] In November 2015 a 14-year-old Tasmanian boy damaged both his eyes after shining a laser pen "... in his eyes for a very brief period of time". He burned his retinas near the macula, the area where most of a person's central vision is ...
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 ZKZM-500 is the subject of a July 2018 article in the South China Morning Post describing a laser gun purported to have been developed by Chinese researchers of the Xian Institute of Optics and Precision Mechanics at the Chinese Academy of Sciences in Shaanxi. [1]
Example of petawatt laser. The Station of Extreme Light (SEL, 极端光物理线站) is laser facility aimed at producing a laser with 100 petawatts (PW) of peak power. The station is currently under construction in Shanghai, China. [1] The laser may be powerful enough to produce matter and antimatter directly from a vacuum [2] (the Schwinger ...
