Laser Gain

Course Details

Field of Study: Electronics Engineering
Course Name: Optoelectronics
Subtitle: Laser Gain

The amount of amplification of the incident beam in a single pass is small, a fraction of a percent/centimeter of travel.
To increase the path length through the sample could use either:
• A very long laser/gain medium.
• Mirrors to reflect the beam back into the sample.

The gain medium is the substance which can support the population inversion, can be solid, liquid or gas.
The combination of the gain medium and the mirrors is called the laser cavity or the optical resonator.
