After the first successful demonstration of a self optimising diode laser with an intracavity spatial light modulator (SLM) in the first part of the project, we now aim to optimise and extend this concept towards concrete goals. The target improvements include a reduction of the achieved pulse widths below 100fs, the integration of power amplifiers to achieve high average and peak powers and, finally, the optimisation of the system directly for examplary applications. In detail, we define the following goals:1. With self optimising dispersion and spectral loss control we aim to realise for the first time sub-100 fs pulses with electrically pumped diode lasers. For this purpose we also plan to implement semiconductor active materials with extra broad gain spectra.2. Our passively modelocked lasers will be additionally synchronously modulated in order to determine whether active modulation might influence the chirp towards a larger bandwidth of the emitted pulses. 3. We expect a further shortening of the pulses by improving the pulse compression with the external compressor. By implementing a second SLM into the compressor, also nonlinear chirp components will be compressed.4. To achieve application relevant output power, we will implement a tapered diode laser amplifier into the system. 5. After implementation of the amplifier, the current control of the amplifier will be included into the evolutionary algorithm in order to analyse whether self phase modulation in the amplifier can be used to obtain larger bandwidths and thus shorter pulses after compression.6. The last goal is the successful operation of the self optzimising system in examplary applications.

在项目第一部分中首次成功地展示了自我优化二极管激光器（SLM）之后，我们现在旨在将此概念优化和扩展到具体目标。目标改进包括将所达到的脉冲宽度降低到100F以下，这是功率放大器以实现高平均功率和峰值功率的集成，最后，直接对系统进行了优化，以直接用于检查应用应用。详细说明，我们定义以下目标：1。通过自我优化的分散和光谱损耗控制，我们旨在首次使用电泵送二极管激光器来首次实现100 fs脉冲。为此，我们还计划实施具有额外广泛增益光谱的半导体活动材料2。我们的被动模型激光器将同步调制，以确定主动调制是否可能影响呼叫的发射脉冲的较大带宽。 3。我们希望通过使用外部压缩机改善脉冲压缩来进一步缩短脉冲。通过将第二个SLM实施到压缩机中，也将压缩非线性chirp组件4。为了实现应用程序相关的输出功率，我们将在系统中实现锥形二极管激光放大器。 5。实施放大器后，放大器的当前控制将包括在进化算法中，以分析放大器中的自相调制是否可用于获得更大的带宽，从而在压缩后较短脉冲。6。最后一个目标是在检查应用程序中成功操作。
