Description
Model 1101-XX-QCW-YYYY-MicroTT-EXT is a cutting-edge high power quasi-CW micro tabletop quantum cascade laser system. This advanced system serves as a robust pulsed source of infrared radiation, delivering over 2 watts of average power at a wavelength of 4.6 µm. The versatility of this system is highlighted by its capability to operate at other wavelengths ranging from 3.8 to 12 µm, catering to a broad spectrum of scientific and industrial applications.
Designed for ease of use and stability, the system is passively cooled and virtually vibration-free, making it ideal for bench top deployment. Its self-contained design requires only an external 20 VDC power source to function, with all necessary pulse shaping and power conditioning electronics housed within. The hermetically sealed package incorporates the QCL and related optics, ensuring a collimated laser beam output. Notably, the system demands no field adjustments and remains stable over extended periods, provided it operates in a stable temperature environment.
The Model 1101-XX-QCW-YYYY-MicroTT-EXT offers the flexibility of internal battery operation, allowing for greater mobility and convenience. With four CR123A batteries, the system can run for over 30 minutes at a 2 W output, with longer runtimes achievable at lower power settings. This feature enhances the system's versatility, making it suitable for various field and laboratory settings.
