What is a Master Laser?

A master laser is a single-frequency laser which is used for, e.g., injection locking of one or several slave lasers. Sometimes, the term master laser is also used for a seed laser of a master oscillator power amplifier system.

A master laser often generates an optical power which is well below the output power of the complete laser system; the injection-seeded slave lasers may then be high-power lasers. The modest power requirements for the master laser make it possible to realize a very low level of laser noise, which may be approximately transferred to the whole system. Also, a larger range for wavelength tuning may be accomplished.

What is a master laser?

What are the key properties of a master laser?

A master laser usually has a modest optical power but provides superior performance, such as a very low level of laser noise or a wide wavelength tuning range. These desirable properties are then transferred to the higher-power output of the overall system.
