-The laser controller has two temperature controllers capable of sub-mK stability(( Sub-mK stability requires a proper thermal design and proper tuning of the temperature controller to the thermal plant. If you did not purchase a D2-100 Diode Laser with your Laser Controller, please read the section on tuning the temperature controller.)) and a 200 mA or 500 mA precision current source based on the Libbrecht-Hall(( Libbrecht and Hall, A Low-Noise, High-Speed Current Controller, Rev. Sci. Inst. 64, pp. 2133-2135 (1993).)) circuit.  The laser controller is designed for very fast current modulation via the servo input enabling high-speed servo control of the laser's frequency.  The current servo input can accommodate input frequencies over 10 MHz and is limited by  the 1 kΩ input impedance. Additionally, an RF port is available for higher frequency modulation.+The laser controller has two temperature controllers capable of sub-mK stability((Sub-mK stability requires a proper thermal design and proper tuning of the temperature controller to the thermal plant.
