Quantum Cascade Lasers
Block Engineering sells widely tunable mid-infrared quantum cascade lasers to universities, research laboratories, and original equipment manufacturers (OEMs).
Our lasers are used in spectroscopy, chemical detection, and other research applications (click for a partial list of research papers). Our QCL modules also serve as the laser engines for Atomic Force Microscopy, Photoacoustic Spectroscopy, and other imaging and life science equipment.
Block offers two quantum cascade laser products:
Mid-Infrared QCL Laser Source for Researchers
Block's LaserTune is a widely tunable laser source for research and academic customers. Covering the key "fingerprint" region of the mid-IR spectrum, Block's LaserTune source offers an extremely fast sweep capability at 25 cm-1 per millisecond. The system supports pulse durations of between 20 to 500 nsec, a repetition rate of up to ~3 MHz, and a duty-cycle of up to 15%.
OEM QCL Modules for Manufacturers
Block also offers the Mini-QCL compact laser module for OEM customers that can be integrated into a wide variety of instruments including IR microscopes, infrared spectrometers, Photoacoustic Spectrometers, (PAS), Cavity Ring-Down spectrometers (CRDS), and Atomic Force Microscopes (AFM).
