Output Coupler |
|
 An output coupler (OC) is a partially reflective
mirror used in lasers to extract a portion of
the laser beam from the optical resonator. Lasers
operate by reflecting light between two or more
mirrors which have an active laser medium
between them. The medium amplifies the light by
stimulated emission. For lasing to occur, the
gain of the active medium must be larger than
the total loss, which includes both unwanted
effects such as absorption, and the intentional
release of energy through the output coupler. In
other words the laser must attain threshold.

◆Frequency
Doubler |
|
 Frequency
Doubler or Second Harmonic Generation (SHG) is a
special case of sum frequency generation if the
two input wavelengths are the same. The simplest
scheme for frequency doubling is extracavity
doubling. The laser passes through the nonlinear
crystal only once. However, if the power density
of laser is low, focused beam, intracavity
doubling and external resonant cavity are
normally used to increase the power density on
the crystals. |

Property and
Application |
|
Plano-Convex
Lens |
L01 |
|
Positive
focus length. Most suitable where one conjugate is more than five
times the other. Also where both conjugates are on the same side of
the lens. |
|
Double-Concave Lens |
L02 |
|
Negative
lens with the form most suited to producing diverging light or a
virtual image, where the input light is converging. |
|
Plano-Concave
Lens |
L03 |
|
Negative
lens with the form most suitable where one conjugates is more than
five times the other, e.g. producing divergent light from a
collimated input beam. |
