Advanced High-Power Pulsed Laser Light System for Precision Spectroscopy

 

Unmatched Speed and Tunability with the MIRcat-QT High-Power Pulsed Laser Light System

For applications demanding rapid, high-quality data acquisition, the MIRcat-QT offers an advanced high-power pulsed laser light system that excels in both speed and tunability. Designed for the most demanding molecular spectroscopy applications, this system delivers uncompromised performance in both continuous wave (CW) and pulsed modes.

 

Advanced Laser Light Source for Superior Ranging and High-Power Sensing

The MIRcat-QT is equipped with state-of-the-art Quantum Cascade Laser (QCL) technology, providing an ultra-broadly tunable mid-IR laser light source. This advanced high-power laser light system offers tuning speeds exceeding 5000 cm⁻¹/s and tuning ranges surpassing 900 cm⁻¹. With peak power output up to 1 W and average power up to 0.5 W, it ensures high signal-to-noise ratios (SNR), essential for accurate spectroscopy, high-power ranging, and other precision applications.

 

Versatile and Modular Design for Custom High-Power Laser Light Applications

The flexible, modular design of the MIRcat-QT high-power pulsed laser light system allows for extensive customization based on specific user needs. It supports up to four pulsed or CW/pulsed modules and can be easily upgraded to accommodate future requirements. An optional visible aiming beam enhances its precision targeting capabilities.

 

Reliable and Safe Operation with Proprietary HFQD™ Circuitry in High-Power Laser Systems

Safety and reliability are critical in high-power laser systems. The MIRcat-QT incorporates proprietary HFQD™ (High-Fidelity QCL Drive) circuitry to protect QCL chips during operation. Its ultra-quiet CW mode with RIN as low as -145 dBc/Hz ensures stable and consistent performance, even in the most demanding environments.

 

Applications of the MIRcat-QT Advanced High-Power Pulsed Laser Light System

The MIRcat-QT advanced high-power pulsed laser light system is ideal for a wide range of applications, including:

  • Standoff Detection: High-power laser light enables long-range sensing.
  • Process Control: Precise laser tuning enhances process efficiency and quality control.
  • Imaging: Ultra-broad tunability facilitates advanced imaging techniques.
