Optical correction methods

From Power Technology, Inc.

A laser diode naturally produces a beam that is divergent, elliptical, and astigmatic. A variety of optical
procedures are available to correct for these deficiencies, procedures that enable a laser diode module to
produce a circular, diffraction-limited beam with very low divergence.

Diode Lasers
Diode lasers use light-emitting diodes to produce stimulated emissions in the form of coherent light output. They are also known as laser diodes.
Lasers
Lasers are devices that produce intense beams of monochromatic, coherent radiation. The word "laser" is an acronym for Light Amplification by Stimulated Emission of Radiation.
Laser Mounts
Laser mounts are devices that keep a laser in position on an optical table.
Solid State Lasers
Solid state lasers use a transparent substance (crystalline or glass) as the active medium, doped to provide the energy states necessary for lasing.  Solid state lasers are used in both low and high power applications.
Alignment Lasers
Alignment Lasers are lasers that create an extremely accurate reference point, line, or shape for aligning machines in industrial processes.
