12 Mar 2009 Based on an ultra-low-noise design (Libbrecht and Hall,‘93) with <100nA rms current noise (below 1 MHz), 1 microA/°C temperature stability, and >10 MHz current modulation servo input. The D2-105 is a precision diode laser current source based on the Libbrecht-Hall* circuit. This ultra-low current noise is ideally suited for precision spectroscopy and metrology applications. Furthermore two-stages of temperature control provide sub-mK stability, ensuring long term frequency stability. A front panel current servo BNC enables high-speed (> 10 MHz) servo control of the laser’s frequency. Additionally, extremely high speed modulation is enabled by a front panel RF port, which is connected directly to the laser current output SMA. Powered with an external power supply (D2-002 or D2-005) or user provided power via a breakout board (D2-001). |
