    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 Doubling Crystal
    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.

     


     
    Filter
    Absorption, and particularly wavelength selective absorption is an important factor in the function of the filters. The two most commonly used absorbers are thin metallic films which are particularly insensitive to wavelength for absorption, and colored glasses which absorb wavelengths varied by as much as several orders of magnitudes in only tens of nanometers. Interference filters are multilayer dielectric thin film devices. Metallic films, colored glasses and thin dielectric films are used in CNI filters.
