The Mamyshev oscillator (MO) is a type of fiber laser capable of producing high-energy laser pulses at a tunable repetition rate. It is a mode-locked laser which uses light traveling within a closed-loop cavity to produce laser emission. Harmonic mode-locking (HML) is an advanced form of mode-locking process where multiple laser pulses are produced within one round trip of light. MOs employing HML are used for several advanced applications such as optical communication, frequency metrology, and micromachining.

The paper argues that the third principle of thermodynamics follows from the second principle, rather than being a separate or independent concept. Professor José María Martín-Olalla of the University of Seville has published a paper addressing a thermodynamics problem that has remained unresolve
