The program package LabII allows to simulate a wide variety of basic experimental setups and devices which can be found in a typical femtosecond laser lab. Since the package runs in the LabView environment this can be done in a very comfortable and graphic way. Several users have contributed special modules that make labII even more attractive, as they allow to study a number of laser-matter interactions. They include diatomic molecules (LabII solves the time dependent Schroedinger equation), three level systems (LabII solves Maxwell Bloch equations) to name a few.

LabII was born at the Institute for Optics and Quantum Electronics (IOQ) in Jena in 1998. Its headquarter is now - since fall 2004 - at the Institute for Applied Physics in Bern (Switzerland) . It shall give assistance to everyone who wants to simulate and plan experiments which involve femtosecond laser pulses.
