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
Power supply has a 5 second startup delay time
Laser is activated by a separate switch
Physical details Size: 28 cm (W), 18 cm (H), 37 cm (D)
Weight: 10 kg
Electrical details 110/220 V, 4 A (max)
Optional modification available for operation from a single 28V DC source with somewhat lower power consumption
