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 e.g. in 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).
