Study Notes
Laser Basics
- The word 'laser' stands for Light Amplification by Stimulated Emission of Radiation.
Laser History
- The first laser was built in 1960 by Theodore Maiman.
Laser Properties
- The property that distinguishes a laser from other light sources is its spatial coherence.
- Spatial coherence enables precision cutting in laser applications.
Laser Characteristics
- A laser beam's ability to stay narrow over great distances is known as its collimation.
- The typical pulse length of a ruby laser is around 20-30 milliseconds.
- Ruby lasers produce light with a wavelength of 694.3 nanometers.
Ruby Laser
- A ruby laser is a type of solid-state laser.
- The ruby rod in a ruby laser is typically pumped by a flash lamp.
- What distinguishes the ruby laser from most solid-state lasers is its three-level energy system.
