Laser controller
Laser supply | • | Provides the necessary laser drive current for the quantum cascade laser (factory adjusted to deliver the specified laser output power) |
Temperature control | • | Provides the necessary drive current for the associated thermoelectric coolers (factory adjusted to provide the needed cooling at the optimum operating point) |
Wavelength control | • | Using proprietary algorithms, provides all necessary internal signals for precisely setting and maintaing the desired wavelength |
• | Front panel control of wavelength selection | |
• | Optional computer control of wavelength slection via USB | |
Modulation | • | Front panel input connector for modulation of the laser output from 1 kHz to 100 kHz (TTL input), limited by the power supply. The quantum cascade laser can be modulated at rates up to 1 GHz with special power supply. |
Protection | • | Laser power supply is equipped with multiple levels of protection for trouble free operation of the QCL |
