Some applications require a laser beam with low divergence.  To reduce θ we must expand the waist of the beam.  This can be achieved by expanding a laser beam with a beam expander.  A beam expander consists of two lenses.  First, the beam is diverged with a short focal length lens and then the diverging beam is re-collimated with a larger beam waist and smaller divergence.  The lenses are positioned like in an inverted telescope.  The light enters in the eyepiece lens and emerges from the objective lens.

In step 6, use the lens paper as in step 5. You may choose to use a 2 inch diameter lens instead of a 1 inch diameter lens for the second lens.  Mount the second lens on a translation stage so it can be translated along the beam direction.  It is then much easier to determine the correct distance between the lenses experimentally.

The viewing angle also changes depending on the refractive index of the lenticular lenses, which is determined by the ratio of the thickness to the number of lines. For the same number of lines, thicker lenses provide a deeper 3D effect, while thinner lenses are better suited for 2D displays.

In this experiment students will construct two types of laser beam expanders, a Galilean and a Keplerian beam expander.

After passage through a beam expander, the divergence of the beam is equal to its original divergence divided by the power of the telescope fo/fe.

For a Gaussian beam of a particular wavelength, the product d0θ is constant.  Therefore, for a beam with a very small beam waist d0 the divergence θ must be large, while for a highly collimated beam with small θ the beam waist d0 must be large.

Keplerian beam expander

A Gaussian beam has a waist, where r1 is smallest.  It either diverges from or converges to this beam waist.  This divergence or convergence is measured by the angle θ which is subtended by the points on either side of the beam axis where the irradiance has dropped if to 1/e2 of its value on the beam axis.

The output of a laser is different than that of most other light sources.  The laser resonator determines the spatial characteristics of the laser beam.  Most lasers have spherical-mirror Fabry-Perot resonators that have Hermite-Gaussian spatial modes.  Usually only the lowest order transverse resonator (TEM00) mode oscillates, resulting in a Gaussian output beam.

The redstone comparator is by far the most misunderstood redstone component. It has one main input, two side inputs and one output.

In step 4 you are supposed to find the initial divergence of the laser beam.  This may be difficult given space restrictions.  Try it by determining the beam diameter at 5 distances from the laser aperture. Record your measurements in a table.  After you have completed your data analysis, compare your results with the specifications of the manufacturer.  For the He-Ne lasers used in the Optics Laboratory you can assume that the beam waist is located at the output aperture of the laser.  Note that d0θ = 4λ/π.

The primary applications of lenticular lenses are "3D stereopsis with the naked eye" and "creating 2D images whose patterns change depending on the viewing angle." This principle is also applied to souvenir cards and keychains, which have lenticular lenses attached to their surfaces. In recent times, there have been advancements in naked-eye stereoscopic displays that do not require 3D glasses.

In step 1 in the workbook, mount the laser assembly so so that the rod and the rod clamp are flush on top.  This assures that you have enough freedom of movement for the lenses.

A lenticular lens is a convex lens whose cross-section is shaped like a fish cake and is generally a sheet of multiple elongated convex lenses in a row. By displaying parallax images or videos on a screen with a lenticular lens attached to the screen, it is possible to achieve stereoscopic vision with the naked eye.

Under the laws of geometrical optics a Gaussian beam converging at an angle of θ should collapse to a point.  Because of diffraction, this does not occur.  However, at the intersection of the asymptotes that define θ, the beam diameter reaches a minimum value d0, the beam waist diameter.  For a TEM00 mode d0 depends on the beam divergence angle as d0 = 4λ/πθ, where λ is the wavelength of the radiation.

For example, when used as a Center Information Display (CID) for in-vehicle use, a single display can simultaneously generate car navigation images on the driver's side and entertainment images such as movies on the passenger side. In the context of a 3D stereoscopic display for the naked eye, two types of images with parallax adjusted for the left eye and the right eye are generated. The conditions of the lenticular lenses are adjusted so that the light from the pixels displaying the respective image data is separated in the direction of the user's left eye and right eye.

Lenticular lenses are often made of materials such as PET or acrylic and are used as sheets consisting of a series of long, thin convex lenses with a cross-section shaped like a fish cake. By attaching this sheet or printing directly on the back of the sheet, effects like "stereoscopic vision" and "objects seen from different viewing angles" can be achieved. This effect is produced when light is refracted by lenticular lenses. Precise alignment of each convex lens of the lenticular lens with the target image or video is crucial to achieve this effect. Misalignment can result in an ineffective display. Lenticular sheets use a numerical value called "lpi" to indicate the fineness of the sheet's surface, so it is important to produce images and videos that match this pitch. For example, 30 lpi means there are 30 lenses per inch and 100 lpi means there are 100 lenses per inch.
