The Profile LDC1000 is a four-channel laser diode controller paired with the ITC 1022 temperature controller and TE 2A thermoelectric cooler module. This system delivers high-power current and temperature stabilization for laser diode arrays, stacks, and single emitters in CW and pulsed operation modes. Built-in microprocessor-based PID control, non-volatile configuration storage, and multiple safety interlocks make it suitable for research, laboratory, and industrial high-power laser applications.
