The LDC-3926 16-Channel Laser Diode Controller offers 16 channels of high power laser diode current source and temperature control in a space saving rack mountable instrument. ILX Lightwave designed the LDC-3926 to meet the increasing pump laser control demands of high power optical amplifiers. With up to 6 A available per channel, the LDC-3926 offers the only 16-channel modular instrument for development and production testing of high power optical amplifiers and pump lasers. Two high current output modules were specifi cally developed for the LDC-3926. A 42W, 6A laser current control module offers 4-wire forward voltage measurement, independent modulation, and enhanced laser diode protection with adjustable forward voltage. A 48W, 6A TEC control module offers precise temperature control with high stability and TE voltage measurement. For even more fl exibility, the LDC-3926 accepts all ILX LDC-3916 control modules.
