  • Current limit
  • Interlock other devices based on temperature control fidelity


The SLICE-DCC is a compact, efficient cw current controller for driving diode, interband, and quantum cascade lasers as well as semiconductor optical amplifiers and tapered amplifiers. Part of the Vescent SLICE series of high-performance, economical photonic control electronics, SLICE-DCC offers two channels of low-noise current control. Proprietary self-adjusting power supply technology automatically sets the compliance voltage to as high as 12 V – but no higher than necessary to drive your load – allowing you to drive a traditional diode or a quantum cascade laser with the same device and the same efficiency. The two channels operate independently – including the automatic compliance voltage.

The SLICE-DCC includes all the features you expect from your current controller, including high modulation bandwidth, power leveling, interlocking, and current limiting & diode protection circuits. Not to mention ease of use through a touch screen or an API command set accessible via a USB port. The unique switching power supply design accepts all standard AC mains voltages and is highly efficient but is also low noise without linear power cost & weight.
