Laser beams slowly spread out. At the Nominal Ocular Hazard Distance (NOHD), the beam has spread enough so that the light intensity (irradiance) directly entering the eye is at the Maximum Permissible Exposure (MPE). Within the NOHD, the irradiance will be above the MPE, which is potential...
The StingerhawkFT-2 Laser Protective Basic Kitincludes glasses which protect against green lasers at 532 nm, blue lasers at 445 nm, and violet lasers at 405 nm. The Optical Density is OD4 at each wavelength, meaning it reduces the laser intensity by a factor of 10,000. The kit costs $...
Pulsar TW is the state-of-the-art high intensity laser for high field science. It offers best-in-class performance with industrial-grade reliability in a compact footprint. This laser... Pulse Duration < 25 fs Peak Power From > 60 TW to > 250 TW ...
Will a pointer of laser damage a security camera? At the midpoint, the pointer of the laser will not threaten and damage the cameras of security. Laser is a girder of light that manufacture heat. With delicate materials, if laser constructs contact, like a sensor of a camera it is the ...
Propagation of high-intensity, high-contrast (<108), 50 fs laser pulses through triangular copper capillaries is experimentally studied. The relative transmission through 20-mm-long, about 50μm wide capillaries is directly measured to be 70% for input intensities up to1017W/cm2. The copper ref...
(intensity in the main pulse divided by the intensity of the pre-pulse) is of the order of 109by considering the pedestal some nanoseconds before the main pulse. The laser transport line from the compressor to the interaction chamber is realized in a high vacuum environment (10−6mbar) in...
Its intensity is maximal on the optical axis, which makes the optical power and intensity nicely concentrated; It has the lowest divergence, so it is often treated as a thin ray of light that doesn’t widen; It is diffraction-limited, which means that when focused, the beam waist is the...

A New Zealand man aimed a laser pointer at police officers who were conducting a bail check on June 3 2018. When the officers arrived, Niki John Gamble-Mackesy, 23, deliberately aimed a green "high-powered" laser pointer [likely over the 1 milliwatt New Zealand limit] directly into...
We have investigated proton acceleration in the forward direction from a near-critical density hydrogen gas jet target irradiated by a high intensity (1018 W/cm2), short-pulse (5 ps) laser with wavelength of 1.054 μm. We observed the signature of the Collisionless Shock Acceleration me...
