What is Laser Optics?

well, you kinda answered your own question. The laser optics refers (here) to the use of mirrors to focus the light on the sample, this is normally used for a fluorescent dye which has been used to stain a part of the cell.

Microphotonics is a branch of technology that deals with directing light on a microscopic scale. It is used in optical networking.\n\nSee link below

Use of a fresnel lens, a lens made up of circular rings that focus the light to the small area of reflecting mirror. This in turn projects the image to the screen. \n\nTake the optic workings of a telescope or microscope:\n\nOptics - microscopes and telescopes all invert the image because if they didnt, it would mean that another lens had to be added, increasing money cost. A lens is convex on both sides. That means the middle is thicker than the edges. A microscope or telescope has two lenses (basically).\nThe objective lens (usually larger and closer to the specimen or object) which allows the image of the object to be reduced to a smaller workable image inside the scope. \nThis image is inverted inside the scope. It is also too small to see with the eye, so you need another lens, the eyepiece. The eyepiece focus's your eye on the image and magnifies \nit so you can see it. Every lens has a focal length, the point at which the image is formed away from the surface of the lens. \n\nOk now we take this to the overhead:\n\nSame principle but in different Direction. You manipulate the object, transparency, over the light source after the light is passed thru the fresnel. The fresnel forms the smaller inverted image on the mirror. It is then reflected to the screen where the focal length is adjusted (moved closer or farther away from the screen )

LASER is the acronym for "Light Amplification by Stimulated Emission of Radiation".  It is, first, a process that is explained by quantum mechanics and statistical mechanics.  At this point, it has come into common use, and can also refer to either the light or the device used to produce this type of light.  It does not have a higher energy than light produced by other means, as the energy only depends on the frequency of light.  It does have a higher intensity concentrated into a smaller area, and much higher coherency than light from the sun or a light bulb.\n\nAlso, all light, regardless of how it is produced, travels at approximately 300,000 km/sec in a vacuum.  That value does not differ from one type of light to another, or one color of light to another.

A laser light as you described is not going to cause eye damage by looking at it as most are lead to believe. That is also true about having a laser pointer being pointed into one's eye. You eyes will become injured more so if you look at the sun.\n\nIf you have nothing better to do but to look at the bottom of your mouse, then you have other problems... ;=)

My son has a cheap red laser pointer (well under $10)\nwhich has a few "lenses" that he can screw on the\nfront to make different patterns.\n\nI don't know if these things are strictly "lenses",\nbut they distort/focus/shape the laser dot to\nlook like a star, a line, or a couple of other\npatterns.\n\nIn any case, one causes the laser pointer to produce a\n"line" rather than a "dot", and that seems like it would\nsatisfy some of your needs.  The width isn't readily\nadjustable, but the the length would be (by covering\npart of the "line" just past the light source).

Light Amplification (by) Stimulated Emission (of) Radiation\n\nMany different types:\n\nRuby rod laser - basically a polished rod of aluminium oxide/chromium oxide (synthetic tuby), surrounded by apowerful flashtube.  - Visible Red\n\nNitrogen laser, co2 laser (gas lasers) fairly efficient by laser standards, inivisble output but can be strong enough to cut metal\n\nsemiconductor - both invisible and red - cheap for low power\n\ndpss  -  diode pumped solid state - these lasers use a "pump" diode which is usually 808nm, tis goes into a sliver of something called vanadate which take in light at 808bm (almost invisible Infra Red) and re-emit it at 1064nM (Invisible. It is then put through a crystal of KTP which halves the wavelength (doubling the frequency) and re-emits at 532nM - bright green

A laser is composed of an active laser medium (gain medium) and a resonant optical cavity.\n\nThe gain medium transfers external energy into the laser beam. It is a material of controlled purity, size and shape, which uses a quantum mechanical effect called stimulated emission to amplify the beam. The gain medium is pumped by an external energy source, such as electricity or light (a flash lamp or another laser). The pump energy is absorbed by the medium, producing excited states. When the number of particles in one excited state exceeds the number of particles in some lower state, population inversion is achieved. In this condition, an optical beam passing through the medium produces more stimulated emission than the stimulated absorption so the beam is amplified. An excited laser medium can also function as an optical amplifier. \nThe light generated by stimulated emission is very similar to the input signal in terms of wavelength, phase, and polarization. This gives laser light its characteristic coherence, and allows it to maintain the uniform polarization and monochromaticity established by the optical cavity design.\nThe resonant cavity contains a coherent beam of light between reflective surfaces so that each photon passes through the gain medium multiple times before being emitted from the output aperture or lost to diffraction or absorption. As light circulates through the cavity, passing through the gain medium, if the amplification in the medium is stronger than the resonator losses, the power of the circulating light can rise exponentially.

Most commonly observed optical effects (refraction, diffraction, reflection) are linear: if you double the amount of light at the source, the results observed also double. Similarly for decreases in the amount of light. There is a linear relationship between source intensity and observed intensity as the light passes through the optics (lens, mirrors, etc.).\n\nNon-linear optics don't behave that way at all. As the light intensity increases, the medium through which the light propagates (the optics) is stressed by the electrical or magnetic field (or both) of the light wave. This stress changes some physical property of the medium, such as its polarization or its refractive index, as a function of the light intensity. The result is a non-linear response of the material to the electromagnetic field of the light.\n\nThis can have some interesting consequences, such as the generation of harmonics of the original wavelength. It is this non-linear mechanism that allows a strong infrared, or near infrared, laser to be be frequency doubled or frequency tripled to produce coherent light at visible or ultraviolet wavelengths.

In optics and physics, a wavefront is a line of points (called a locus) having the same phase. For a wave propagating in 3 dimensions, the locus is a surface.

Light Ampliification through the Stimuated Emmision of Radiation. It is what laser stands for, and signifies how the light is polarized and focused through mirrors and radioactive gases.

A laser (from the acronym Light Amplification by Stimulated Emission of Radiation) is an optical source that emits photons in a coherent beam. The verb to lase means "to produce coherent light" or possibly "to cut or otherwise treat with coherent light", and is a back-formation of the term laser.\n\nLaser light is typically near-monochromatic, i.e. consisting of a single wavelength or color, and emitted in a narrow beam. This is in contrast to common light sources, such as the incandescent light bulb, which emit incoherent photons in almost all directions, usually over a wide spectrum of wavelengths.
