We apply for a frequency-stabilized Ti-sapphire laser SolsTiS plus pump laser fabricated by the company M squared, which shall be extended with corresponding modules so that it can be operated across the whole spectral range from the near-UV (> 200 nm wavelength) to the near-IR (< 4,5 micrometer wavelength). This large range is necessary to study the different material classes addressed at the chair Experimentelle Physik 2 together with our collaboration partners. The material spectrum has been recently extended from traditional III-V and II-VI semiconductors to materials such as colloidal nanostructures, perovskites and 2D-materials, the band gaps of which can be varied across this spectral range by changing structural composition and size. The laser system of the company M squared is the only one commercially available, which can cover this wavelength range in combination with excellent parameters such as linewidth (< 0,5 MHz, in the visible < 100 kHz), sufficient emission power (at least several tens of mW at high temporal stability), and low intensity noise (< 0,3 % rms). Also the excellent beam quality in the TEM00-mode has to be mentioned. In addition, the system is very tightly arranged and robust in combination with full automatization, ensuring a flexible operation.

我们申请频率稳定的Ti-Sapphire激光Solstis加上由M平方制造的泵激光器，该泵可以用相应的模块扩展，以便可以在整个频谱范围内操作，从近距离（> 200 nm波长）到近IIR（<4,5千分表波长）。对于研究主席实验Physik 2与我们的协作伙伴一起研究的不同材料类是必要的。该材料光谱最近已从传统的III-V和II-VI半导体扩展到诸如胶体纳米结构，钙钛矿和2D材料等材料，通过更改结构组合和大小，可以在该光谱范围内变化的频带间隙。公司M平方的激光系统是唯一可用的一个商业可用，可以覆盖该波长范围，并结合出色的参数，例如lineWidth（可见<100 kHz），足够的排放功率（至少在高暂时稳定性下的MW），以及低强度噪声（低强度噪声）。此外，还必须提到TEM00模式中出色的光束质量。此外，该系统非常紧密地布置和强大，并结合完整的自动化，确保了灵活的操作。
