Understanding Laser Beam Parameters Leads to Better System
... divergence is the derivative of the beam radius with respect to the axial position in the Far Field. This definition yields a divergence half-angle, and further depends on the definition of the beam radius (or, diameter). Sometimes, full angles are used which results in twice as high angles. Therefo ...

This concept makes us think about these designs and all its variables, depending on the principle which have been built upon. Therefore we have conducted several experiments, to test the possibility of this con ...

Ultrafast Optics: Tools and Techniques
... Now that we know how to produce ultrashort, intense pulses, the next question is, what can we do with them? The Kapteyn/Murnane group has been working on the applications of ultrafast lasers for the past ten years and has pioneered many of the methods found in their labs. The main physical process t ...

Such a system could produce light, but it would be emitted in all directions and would behave like ordinary monochromatic light. In order to produce a laser beam, a feedback mechanism is needed to amplify and to ...

Laser beam profiler
A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path. Since there are many types of lasers — ultraviolet, visible, infrared, continuous wave, pulsed, high-power, low-power — there is an assortment of instrumentation for measuring laser beam profiles. No single laser beam profiler can handle every power level, pulse duration, repetition rate, wavelength, and beam size.
