Laser Controller for Optical Amplifiers

	This laser controller is for driving the pump laser in optical amplifiers, such as Raman amplifier and EDFA, with high stability and reliability. It drives the laser in four modes: constant current, constant laser power, constant output power, and constant gain. It also provides these protection functions: over current, over laser power, over output power, and over gain.
