PID Temperature Control

Stability of the temperature of an active D2-100 laser controlled by the SLICE-QTC

The SLICE-QTC PID Temperature Controller features four independent precision temperature controller channels for TECs or heaters for temperature stabilization and control of lasers, semiconductor optical amplifiers, tapered amplifiers, optical cavities, PICs, and non-linear & photonic crystals. The loops can be nested or control four separate systems.  With widely adjustable PID corners and gain, it is possible to stabilize the temperature of your plant with sub-millikelvin temperature stability and set point resolution. Download our application note on stabilizing large thermal loads to sub-millikelving stability.

Features like slew rate control and an output trigger allow you to trust your delicate photonic devices such as doubling crystals to the SLICE-QTC.  You can set a maximum rate of temperature change and have confidence it won’t be exceeded. Safeguard your laser diodes by automatically shutting down the current if the the temperature goes out of range.  Easily tune the PID temperature loop using the loop performance monitoring system.

The Vescent Photonics SLICEs of precision photonics control. Individually or working together, SLICE provides the performance you need on your benchtop, laser table, or in a rack.
