TITLE: High Power Tunable Laser System at 885.4 nm Requesting Lab/Division/Group: PML / Time and Frequency / Atomic Devices and Instrumentation

NB688000-25-01390

General Statement of Need For experiments on research of a compact optical frequency reference based on Cesium we require a tunable semiconductor 885.4 nm laser system with at least 75 mW of power available coming out of a single mode optical fiber after an optical isolator providing isolation of at least 60 dB. For this experiment we require a laser with a narrow linewidth of less than or equal to 100 kHz in a 0.1 s integrated bandwidth. For stable operation, we require the output of the laser to be able to be directly coupled into a single mode polarization maintain fiber, mounted directly to the laser head. The laser must have a mode hop free tuning range of >10 GHz for stable operation. The laser system must also include necessary control electronics for operation of the laser including current and temperature control and piezo scanning. The laser system must have the ability for coarse wavelength tuning from 870 nm to 895 nm to be able to target additional transitions in cesium.
