FFC-PDM Pump Diode Module

PDM Pump Diode Module for frequency combs, mode-locked lasers, and amplifiers

Contact us for assistance in purchasing this item.

Pump Diode Module for pumping mode-locked Er:doped fiber oscillators and EDFAs in the FFC-CM frequency comb optical module and other Vescent fiber products.  This board-level device will drive any combination of up to four oscillator and amplifier pump diodes.  Low current noise is combined with temperature control and low power consumption to yield an ideal pump control system for development of a deployed optical frequency comb.

User to supply +5, ±15 VDC, a thermal reservoir for product baseplate and low-vibration air circulation (fan).
