A facility for spectrally high-resolution cw spectroscopy on solids is to be built. The core piece is a user friendly, tunable cw laser system, which on the one hand allows narrow band excitation with defined absolute wavelengths and on the other hand covers a wide wavelength range (max. 300-3000 nm). The excitation laser system will be used flexibly for photoluminescence and photoluminescence excitation spectroscopy (PLE) of excitonic resonances and color centers, as well as for optical detection of magnetic resonance, Raman spectroscopy and spectroscopic ellipsometry.

将建造用于固体上频谱高分辨率CW光谱的设施。核心部分是一种用户友好，可调的CW激光系统，一方面允许具有定义的绝对波长的狭窄频段激发，另一方面允许范围覆盖宽的波长范围（最多300-3000 nm）。激发激光系统将灵活地用于激发谐振和色中心的光致发光和光致发光激发光谱（PLE），以及磁共振，拉曼光谱和光谱椭圆的光学检测。
