NettetCareer. Eacott dropped out of high school at the age of 15 and started working in his family's construction business. He originally began posting videos of demolition in slow motion on YouTube, under the name "CrushSlash". After getting his recording equipment stolen, he registered the "LazarBeam" YouTube gaming channel on 4 January 2015; … Lasers are distinguished from other light sources by their coherence. Spatial (or transverse) coherence is typically expressed through the output being a narrow beam, which is diffraction-limited. Laser beams can be focused to very tiny spots, achieving a very high irradiance, or they can have a very low divergence to concentrate their power at a great distance. Temporal (or longitudinal) coherence implies a polarized wave at a single frequency, whose phase is correlate…

NettetWhat are the potential risks and side effects? Pulsed-dye laser treatment has been used since the 1980s to remove port-wine stains on both infants and young children. Since then, extensive research and many procedures have determined that this treatment is safe. While there are no serious side effects, some patients will experience mild swelling or …

NettetThis is achieved for CO 2 lasers by the introduction of what are known as phase retarding mirrors into the beam delivery systems. Either two 1/8 wave phase retarder can be used, or a single 1 / 4 wave phase retarder. The orientation of these mirrors is important to the direction of the polarisation vector in the incident laser beam.
