The development, the underlying technology and the current status of the fully diode-pumped solid-state laser system POLARIS is reviewed. Currently, the POLARIS system delivers 4 J energy, 144 fs long laser pulses with an ultra-high temporal contrast of 5×1012 for the ASE, which is achieved using a so-called double chirped-pulse amplification scheme and cross-polarized wave generation pulse cle...
A relatively inexpensive and versatile degenerate four-wave mixing setup is described utilizing a nitrogen laser pumped dye laser. Samples can be screened rapidly, which is demonstrated with the example of a semiconductor doped glass having a nonlinear susceptibility x((3)) ~ 10(-11)-10(-10) esu.
We report and discuss our main results for the multimode dynamics of a Fabry-P erot laser in diierent situations above threshold: mode beating and mode-hopping. A Travelling Wave approximation has been used together with a model with an asymmetric dynamical gain for the semiconductor laser which captures important features needed for the understanding of multimode dynamics.
A discussion of three topics in the eld of non linear optics is presented We begin with the Colliding Pulse Mode locked CPM Quantum Well QW laser A large signal model consisting of a wave propagation equation for the electrical eld and a rate equation model for the material response is derived The wave propagation equation of the electrical eld is derived from Maxwell s equations in the slowly ...

As optical communication systems continue to advance in speed and complexity, the demand grows for high-speed devices to perform wavelength conversion, multiplexing, and switching operations. Semiconductor diode laser amplifiers exhibit large and ultrafast optical nonlinearities that make them promising candidates as the basic building blocks for such all-optical devices. The primary goal of th...
