The SK305 Linear TEC Controller was designed for high-performance thermal stabilization of laser diodes. In order to achieve low-noise operation, the SK305’s circuitry relies on a purely analog design, eliminating inherent broadband noise associated with switched-mode topologies. Self-heating errors are also minimized by using low excitation current. The provided PID should be suitable for most laser diodes. Nevertheless, for very slow thermal systems, the internal PID can be bypassed in order to rely on a remote compensator: the SK305 is then used to acquire the sensor resistance and to drive the TEC actuator using the internal current source. Associated with the SK657 Ultra-Low Noise Current Source, the SK305 is well suited to controlling low-power laser diodes when noise is a primary concern. Like all modular instruments in the SK-Series, the SK305 Linear TEC Driver can be operated stand-alone or within a platform where several modules can be assembled to configure a specific control or measurement system.
