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.

在项目的第一部分成功演示了带有内腔空间光调制器(SLM)的自优化半导体激光器之后，我们现在的目标是优化和扩展这一概念，以实现具体目标。目标改进包括将实现的脉冲宽度减少到100fs以下，集成功率放大器以实现高平均功率和峰值功率，最后直接针对示例应用对系统进行优化。具体地说，我们定义了以下目标：1.通过自优化色散和光谱损耗控制，我们的目标是首次实现电泵浦半导体激光器的亚100ps脉冲。为此，我们还计划实现具有超宽增益谱的半导体活性材料。我们的被动锁模激光器将被额外地同步调制，以确定主动调制是否可能影响向发射脉冲的更大带宽的啁啾。3.我们期望通过使用外部压缩器改善脉冲压缩来进一步缩短脉冲。通过在压缩机中实施第二个SLM，非线性啁啾分量也将被压缩。为了获得与应用相关的输出功率，我们将在系统中实现一个锥形半导体激光放大器。5.在放大器实现后，将放大器的电流控制纳入进化算法，以分析是否可以利用放大器中的自相位调制来获得更大的带宽，从而获得更短的压缩后脉冲。最后一个目标是自我优化系统在范例应用中的成功运作。
