Low-noise amplifier module TOPTICA Photonics AG
The operation of a diode laser in spectroscopic applications requires highly stable control of the laser's driver current. The current control DCC 110 meets this requirement. The design permits usage with both anode-grounded and cathode-grounded laser diodes. A BNC modulation input connector allows for external modulation of the laser current or output power. An additional BNC connector provides a signal for monitoring the internal photo diode current of a laser diode. Two versions of the DCC 110 are available, with output currents up to 500 mA, or up to 3 A for high-power diodes.
Specifications
- output current range 0... 500 mA (DCC 110/500 mA)
or 0... 3 A (DCC 110/3)
- coarse switch for range selection of output current in steps of 50 mA
- fine tuning of output current or optical power by precision trimmers
- stabilization of constant output current and output power
- operation of laser diodes / photo diodes in any combination of polarity
- calibration of the photo diode current IPD for optical power monitoring
- external modulation of output current up to 10 kHz
- low noise: < 3 µA (DC to 1 MHz, 500 mA version) and < 10 µA (3 A version)
- width: 12 HP (60 mm)
- control module optimized for operation of the grating stabilized diode laser DL100
