Single-frequency emission from a YAG:Nd³⁺minilaser with wavelength tuning

Abstract

The theoretical investigation of time-dependent quantum systems requires the solution of the time-dependent Schrödinger (Dirac) equation. The basis generator method presented here allows a systematic construction of dynamically adapted wavefunctions based on a decomposition of the Hilbert space into a hierarchical structure of finite subspaces. For the class of interactions obeying an inverse integer power law, e.g., Coulomb and polarization interactions, an explicit representation of the dynamically optimized basis set is given.

“…With such a value of N, ␦l becomes close to or even less than the value of ␦d. The loss difference for modes with such close node locations is near a few tenths percent, 13 which is sufficient for mode selection in a laser that functions slightly over threshold. However, a pure MTF selector cannot provide precise mode selection at higher pump levels.…”
