Seed Lasers

Definition: lasers which are used for generating some seed light into an amplifier or another laser

A seed laser is a laser the output which is injected into some amplifier or another laser. This is done in, e.g., the following situations:

Typical types of seed lasers are small laser diodes (single-frequency or gain-switched), short-cavity fiber lasers, and miniature solid-state lasers such as nonplanar ring oscillators (NPROs).

cover of print encyclopedia

Since October 2008, the Encyclopedia of Laser Physics and Technology is also available in the form of a two-volume book. Maybe you would enjoy reading it also in that form! The print version has a carefully designed layout and can be considered a must-have for any institute library, laser research group, or laser company.

You may order the print version via Wiley-VCH.
