5.3 The Three-Level Laser System 101 5.3 The Three-Level Laser System In the last section we saw that one cannot create a steady-state population inversion between two levels just by using pumping between these levels. Thus in order to produce a steady-state population inversion, one makes use of either a three-level or a four-level system. In this section we shall discuss a three-level system

Comprehensive Four-Level Laser Model With Power Conservation Part II: Laser Amplifiers, Resonators, and System Considerations David C. Brown, Member, IEEE Abstract—In this paper, the second of a two-part manuscript, we extend the comprehensive kinetics model of Part I to treat four-level solid-state amplifiers and resonators, followed by the presentation of a detailed systems model …

Rate Equations Three-Level System Introduction: Consider the 3-level scheme 2.3.1-1. Under which condition can the upper pump level 3 be eliminated, so that the 3-level system can be replaced by an e ective 2-level system? 1) Write down a complete set of rate equations for the 3-level system. Assume that the states are not degenerate and that no laser eld is present (which can be ensured for
