LaserTune™: Widely Tunable Mid-Infrared Quantum Cascade Laser

An R&D 100 Award Finalist

Block Engineering's LaserTune is a pulsed mid-IR Quantum Cascade Laser (QCL) source designed to meet the challenging requirements of the research community.

LaserTune's integrated "single box" design offers a gap-free tuning range of 5.4 to 12.8 microns in the mid-infrared region. No external power supply or control peripherals are required.

The laser can be programmed to operate in several modes, including Move Tune (manual control), Step Tune with programmable steps, and Sweep Tune with programmable sweep parameters. LaserTune offers an extremely fast sweep capability at 25 cm-1 per millisecond.

The system supports pulse durations of between 30 to 300 nsec, a repetition rate of up to ~3 MHz, and a duty-cycle of up to 8%. The pulses can be internally triggered at regular intervals with an available sync-out signal. External triggering is also supported. The beam size is roughly 2 mm x 4 mm, with industry leading pointing stability.

Key Benefits & Advantages

  • Configurable with one to four mid-IR lasers to achieve your desired gap-free wavelength range up to 5.4-12.8 µm
  • Wavenumber sweeps, step functions, or static wavenumber control
  • MCT detector option provides an all-in-one spectrometer capability
  • On-board software allows you to easily control the laser and synchronously collect the detector signal to produce a complete exportable spectra
  • SDK provided enables rapid integration

The LaserTune is also available to use with Block's MCT IR Detector module. Please visit the MCT page for additional information.
