Titan-Saphir Lasersystem (UV-NIR)

我们申请的是M方公司制造的频率稳定的钛蓝宝石激光器SolsTiS +泵浦激光器，该激光器需要扩展相应的模块，使其可以在近紫外（波长0 ~ 200 nm）到近红外（波长< 4.5微米）的整个光谱范围内工作。这个大范围是与我们的合作伙伴一起研究在Experimentelle Physik 2椅子上讨论的不同材料类别所必需的。最近，材料光谱已经从传统的III-V和II-VI半导体扩展到胶体纳米结构、钙钛矿和2d材料等材料，这些材料的带隙可以通过改变结构组成和尺寸在该光谱范围内变化。M squared公司的激光系统是唯一一种商用激光系统，它可以覆盖该波长范围，并具有出色的参数，如线宽（< 0.5 MHz，可见光< 100 kHz），足够的发射功率（在高时间稳定性下至少几十mW）和低强度噪声（< 0.3 % rms）。此外，还必须提到tem00模式下出色的光束质量。此外，该系统结构紧凑，坚固耐用，并结合全自动化，确保了操作的灵活性。

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.
