Laser diodes are very sensitive to electrostatic discharge (ESD), current/ voltage transients, and temperature changes, and extra care must be taken to ensure the laser diode is protected during all operating conditions. Unlike general-purpose power supplies or current supplies, laser diode drivers, mounts, and cables greatly improve the protection of laser diodes and allow low noise operation. A temperature controller helps stabilize the temperature of the laser diode packages, which provides for safe operation and wavelength stability of the laser. For fast and reliable characterization, an optical power meter and integrating sphere-based photodiode detectors are often employed where a good understanding of optical measurements is required.
