Overview
The FP4516 Laser Controller is a stand-alone solution for open-loop drive of a multisection tunable laser. It has integrated sources providing five channels of independently programmable output current. It provides separate TEC control for laser and package and read-back of all laser section voltages, TEC currents, laser temperature and case temperature. A simple GUI for control over RS232 interface is included. Compatible with all of our tunable laser products.
