introduces the basic principles of light, lasers and laser safety that are needed to study specific types of laser systems. It also provides exposure to the topics that make up the foundation for studying the applications of lasers in telecommunications, electro-optical displays, biomedical
What is a laser? Different types of laser systems. What makes lasers special? They produce a directional beam. They have a narrow spectrum (or bandwidth). They are coherent. Rate of absorption/stimulated emission dependent on no of photons & number of atoms in lower/upper state. We want lots of this....
This university textbook describes in its first three chapters the fundamentals of lasers: light-matter interaction, the amplifying laser medium and the laser resonator. In the fourth chapter, pulse generation and related techniques are presented.
This introductory lesson is intended for people who need to understand the basic principles of how lasers work and their main properties. It will also present the different types of lasers available today.
Most light in the universe is emitted by atomic and molecular vibrations. Nuclei in molecules vibrate with respect to each other. Nuclei in molecules rotate. This process has no analog in classical physics - it can only be understood with quantum mechanics! With this, we can write a rate equation for the population density of the two states.
Lasers are devices that produce intense beams of light which are monochromatic, coherent, and highly collimated.
