Carbon Dioxide Lasers Carbon dioxide lasers are one of the most powerful lasers ever constructed. The word “LASER” stands for Light Amplification by Stimulated Emission of Radiation. Lasers are devices that amplify light and produce light beams, ranging from infrared to ultraviolet. A light beam is consistent when its waves or photons, increase while mixing together. Laser light can be extremely intense, highly directional and very pure in color. Gas lasers such as the carbon dioxi

INTRODUCTION Holography is a method of obtaining three-dimensional photographic images. These images are obtained without a lens; the pattern recorded on a photographic plate is called a hologram. On the other hand image formation refers to the process of producing and refining images, various methods are used in order to achieve this. Some common examples include the use of double lens optical systems, spatial filtering, matched filtering and phase contrast microscopy. An exhaustive treatme
