Temperature Control for Laser Diodes: 

• Since many parameters depend on the temperature of the laser diode, it is important to set and maintain a stable temperature using a thermo-electric temperature controller.
• Most laser diode applications use Thermoelectric (TE) coolers based on the Peltier Effect to maintain a constant temperature. TE modules are semiconductor “heat pumps” that move heat from one side of the device to the other. Depending on the direction the current flows through the TE cooler, you can either heat or cool a laser diode.

Product Specifications: 

• Several types of temperature sensors are used: thermistors, I.C. sensors, and platinum resistive temperature devices (RTDs). The most commonly used is the thermistor because of its small size and fast response time. Thermistors and RTDs are nonlinear resistance devices. Both require a small accurate current source to bias them. Changes in temperature result in resistance changes, with the voltage drop across the device proportional to temperature. Each device has a characteristic equation that converts resistance to temperature.
