Answer:
The purpose of a report on optical fiber is to equip the reader with a basic undertaking of optical fiber and its various applications. It supplies not only the information of optical fiber but also its principle and history with other details.
We are grateful to our Physics teacher Mr. Khem Poudyal for his encouragement in making this report. We are also grateful to library of Pulchowk College for its immense support in preparation of this report. We must not forget to thank Mr. Harish Chandra Manandhar and Department of Mechanical Engineering for support in composing this text. Without their help this report would not have come to this form.
Answer:
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "Light Amplification by Stimulated Emission of Radiation".
I. Specific Laser Types:
Helium Neon Laser: The first CW system was the helium neon (HeNe) gas mixture. ...

Other Lasers:
Basic Principles of Lasers. To explain the process of light amplification in a laser requires an understanding of the energy transition phenomena in the atoms of its active medium. They include: spontaneous emission, stimulated emission/absorption and non-radiative decay.
