Coming Soon

Low Noise Laser Controller


  • Lowest-noise current source available!
  • High-modulation bandwidth
  • Servo and RF inputs
  • Two channels of PID temperature control
  • Accepts variable AC line voltages without sacrificing low-noise


  • Diode lasers, QCLs, & ICLs
  • Tapered and semiconductor amplifiers

The SLICE-LC Laser Controller continues the Vescent tradition of offering the absolute lowest noise current controller.  Also incorporated in the SLICE-LC is a pair of PID temperature control loops for stabilizing the laser and its housing.

Proprietary new power supply technology eliminates the need for a traditional linear power supply.  Heavy and expensive, fixed VAC-input power supplies are a thing of the past – even when the lowest noise is an absolute must-have.

The Vescent Photonics SLICEs of precision photonics control. Individually or working together, SLICE provides the performance you need on your benchtop, laser table, or in a rack.
