SR300 Estérel- Laser Diode Controller Electronics

The lowest noise, highest bandwidth and most flexible of any commercially available products


The SR300 is the ideal instrument for controlling the current and the temperature of diodes laser. Including ultra-low noise current sink, sub-mK temperature controller and modulation inputs, the SR300 is the right choice to meet the requirementsof the most demanding applications. The SR300 hardware is based on the modular instruments of the SMC-Series Diode Laser Controller, which can be also ordered separately.
From modular instruments to complete turn-key solutions, Sisyph provides flexible and high-performance electronics for cutting-edge research and engineering.
