The SLICE-DHV is a low-noise high-bandwidth amplifier for controlling piezoelectric transducers and electro-optic modulators.  Designed for controlling pzt-driven tuning elements in ECDLs, it will interface easily with home-built or 3rd-party laser system allowing optimum control.

The SLICE-DHV features two gain levels: a traditional 20x which gives the user access to the full 0-200 V range with a 0 to 10 V input signal.  The SLICE-DHV can also operate at a gain of one (in conjunction with a DC bias) allowing lower-noise control of a 10 V range.  A wide output range (0-200 V), high current capacity (±250 mA), and low noise (<150 µV rms) makes this amplifier ready to take on any number of high-voltage chores.

Designed to control the repetition rate of a mode locked oscillator, the SLICE-DHV features very high control bandwidth.

Proprietary power supply technology allows the elimination of bulky & expensive linear power supplies while not sacrificing noise performance.

The SLICE-DHV is a two channel amplifier offering the economics of scale.
