S-polarization

Whether a laser is p-polarized or s-polarized depends on the laser design and the components in the laser cavity. Some lasers may emit light with a random polarization state, while others, by design, may produce a specific polarization. Diode lasers, for example, often emit naturally polarized light due to the geometric shape of the gain region and cavity design.

This applet also considers refraction, convergence, and divergence of light as it passes through the lens from the left-hand side of the applet. Important values are delineated on the optical axis of the lens(es). The values F and F' are real and imaginary focal points (respectively), O is the object being imaged and I is the point where the image occurs. In situations where a real focal point occurs, the effects of optical aberrations are illustrated as separately colored (red and green) lines of focus.

Laser light can be either p-polarized (parallel) or s-polarized (senkrecht/perpendicular), depending on the orientation of the electric field vector with respect to the plane of incidence, when the light is incident upon a reflective surface.

S-polarized light is reflected differently compared to p-polarized light, especially at angles far from normal incidence. These differences are exploited in various applications where the polarization of light is critical, such as in polarimetry or in reducing glare in imaging systems.

This tutorial explores the effect that lens shape can have on the interaction between an optical element and the light passing through it. Each side of the "window" is adjustable to produce a concave or convex surface using the sliders below.

Polarization

P-polarized light can be preferentially transmitted or reflected by certain optical components, such as beamsplitters or polarizers. The reflection of p-polarized light at nonmetallic surfaces can be minimized at a certain angle of incidence known as Brewster's angle.

P-polarization, short for parallel polarization, refers to light waves with the electric field polarized parallel to the plane of incidence. The plane of incidence is defined as the plane that spans the incident, reflected, and refracted rays. When the electric field component is parallel to this plane, it is p-polarized.

In practical use, one can manipulate the polarization state of laser light using polarizing optics, such as waveplates, to convert one polarization state to another or using polarizers to select a particular polarization state.

S-polarization, short for senkrecht polarization or perpendicular polarization, occurs when the electric field vector is perpendicular to the plane of incidence. This orientation tends to have higher reflection coefficients at surfaces when compared to p-polarization.
