Block Engineering's LaserTune is a turnkey, compact-packaged quantum cascade laser system that covers a tunable gap-free mid-infrared range of 5.4 to 12.8 microns. The full range is covered by packaging four QCL modules in the system. However, for customers who do not need the maximum wavelength range, the system can be configured with 1, 2, or 3 modules instead. Gap-free tuning is maintained in narrower configurations.

No external power supply, control peripherals, or external cooling systems are required. The LaserTune 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.

Quantum Cascade Lasers (QCLs) are tunable lasers that can make controlled incremental shifts in wavelength output. This enables the incredible power of lasers to be applied to broad-band spectroscopy applications where previously there were no solutions. Block’s external cavity QCLs are effective for producing widely tunable systems and providing broadband tuning at microsecond speeds while still compact and multi-modal.

Our QCLs operate in “pulsed” mode (as opposed to “continuous wave”) for operating in a wide range of environments without requiring expensive and bulky external cooling. In addition to the first and only ruggedized QCL systems designed for manufacture and scalability, we also offer the expertise and collaboration to determine the best laser for your application.

Both the Laser Tune-S (single laser) and Laser Tune-M (1-4 lasers) models have an intuitive software interface that is simple to set up and operate in one of 3 modes: Ramping smoothly through a range of wave numbers (WNs), stepping through discrete WNs, or residing at a single WN. The pulses can be internally triggered at regular intervals with an available sync-out signal, or can be initiated by your trigger input.

Laser Tune’s flexible programming platform provides an industry leading sweep speed capability at 25 cm-1 per millisecond, a wide range of pulse durations, fast repetition rates, and a widely adjustable duty-cycle that may be dynamically varied. With a tightly collimated beam, industry-leading thermal/temporal stability, and exceptional spectral accuracy, this rugged system is a reliable tool on any optical bench. The MCT detector option provides all-in-one spectrometer capabilities. On-board software allows you to easily control the laser and collect the detector signal to produce complete exportable spectra. The compact, rugged, plug-and-play design makes Laser Tune a reliable instrument for your lab.

The MCT (Mercury-Cadmium-Telluride) Infrared Detector Module is a thermoelectrically cooled detector element and preamplifier package optimized for acquiring spectral data when coupled with LaserTune-M. The module operates at room temperature without requiring liquid nitrogen or other cooling techniques. Users can configure a spectrometer in a variety of ways for applications such as IR spectroscopy, and spectral data is acquired and available for analysis and storage. The detector module is also optimized for the emission profile and fast scan rate of the LaserTune QCL system. Since the module represents the same hardware employed in Block’s spectrometer system, users get maximum versatility without sacrificing system performance.
