1. Overview and Significance

• dN2/dt = Rpump − N2/τ2 − (σΦ)N2
• Output when gain length L satisfies gL ≥ losses (threshold condition).

The behavior of a laser can be described by a set of rate equations that describe the dynamics of the gain medium and the optical field. The rate equations are: laser fundamentals silfvast pdf 2021

• Q-switching: Store energy in gain medium, then rapidly increase Q to produce high-energy short pulses (ns).
  1. High-power lasers: The development of high-power lasers has enabled new applications, such as laser-based material processing and laser-based medical treatments.
  2. Ultrafast lasers: Ultrafast lasers have been developed for applications, such as multiphoton microscopy and ultrafast spectroscopy.
  3. Quantum lasers: Quantum lasers have been developed for applications, such as quantum computing and quantum communication.

  Weaknesses

  1. Carrier rate equation: This equation describes the dynamics of the excited state population in the gain medium.
  2. Photon rate equation: This equation describes the dynamics of the optical field in the resonator.
