Injection seeders are devices to direct the output of small "seed" lasers, into the cavity of a much larger laser to stabilize the output of the larger laser. Most seed lasers are continuous, stable, single frequency lasers that lie within the linewidth of the material for the larger laser. These can also improve spatial profiles, reduce variations in the output energy from pulse to pulse, and smooth out temporal variations within the pulse. Seed lasers are usually pulsed, and contain an output at a single frequency. This is much better that having a number of longitudinal modes at different frequencies. Injection seeders also reduce the amount of jitter in the timing of the pulse. Some commercial models of these seed injectors also use semiconductor diodes as the seeding source.
