A laser line level is a tool combining a spirit level and/or plumb bob with a laser to display an accurately horizontal or vertical illuminated line on a surface the laser line level is laid against. Laser line levels are used wherever accurate verticals and horizontals are required, typically in the construction and cabinetry industries.
F-center laser 2.3-3.3 μm Ion laser Spectroscopy Optically pumped semiconductor laser 920 nm-1.35 μm Laser diode Projection, life sciences, forensic analysis, spectroscopy, eye surgery, laser light shows. The lasing medium is a semiconductor chip. Frequency doubling or tripling is typically done to produce visible or ultraviolet radiation.
M 2 is useful because it reflects how well a collimated laser beam can be focused to a small spot, or how well a divergent laser source can be collimated. It is a better guide to beam quality than Gaussian appearance because there are many cases in which a beam can look Gaussian, yet have an M 2 value far from unity. [1]
CPA for lasers was introduced by Donna Strickland and Gérard Mourou at the University of Rochester in the mid-1980s, [2] work for which they received the Nobel Prize in Physics in 2018. [3] CPA is the technique used by most high-powered lasers in the world.
The third laser chain, beamline C, could produce up to ~200 J at 1054 nm, or could be frequency doubled to 527 nm at ~100 J in the longpulse mode with the same pulse duration variability as beams A and B; or could be used in the Trident enhancement configuration allowing the ~200 J beam to be compressed via CPA to ~600 fs and ~100 J, producing ...
Line laser with interchangeable lenses. A line laser is a device that employs a laser and an optical lens to project the laser beam as a line rather than a point (e.g. laser pointer). This may be achieved by passing the beam through a cylindrical lens or a Powell lens. [1]
