MIRcat-QT™

RAPID-SCAN, ULTRA-BROADLY TUNABLE MID-IR CW/PULSEDLASER SYSTEM
Demanding Mid-IR spectroscopy applications such as
nanoscale and microscale chemical imaging benefit greatly
from rapid, high-SNR data acquisition. However, until now,
Mid-IR laser sources required compromises in beam quality
and wavelength fidelity to achieve high scan speeds. With
the introduction of the new MIRcat-QT, you can now havesuperior beam quality, wavelength fidelity, and fast continuous
scanning (>1,000 cm-1 at 5 Hz) all in one ultra-broadly tunable,CW/pulsed Mid-IR laser.
Incorporating the next generation of Daylight’s field-proven
Quantum Cascade Laser (QCL) technology, MIRcat-QT delivers
uncompromised performance in application-critical areas. This
includes: tuning speeds to >30,000 cm-1/s, tuning ranges to>1,000 cm-1, CW RIN as low as -145dBc/Hz, peak power output
up to 1W[2], average power output up to 0.5W, and wavelength
repeatability as low as <0.1cm-1[2]. In addition, MIRcat-QT
provides a single TEM00 output beam, which enables highefficiency fiber coupling.

MIRcat-QT’s flexible, modular design allows users to factoryconfigure their system for up to four pulsed or CW/pulsed
modules, upgrade it later, or add a visible aiming beam6.
With Daylight‘s proprietary HFQDTM (High-Fidelity QCL Drive)
circuitry, your QCL chips are protected. With a GUI and SDK
command set included as standard, MIRcat-QT users cancontrol wavelength set-points, scans, power, triggering, pulsewidth, duty cycle, and repetition rate in pulsed operation.
MIRcat-QT brings new capabilities and agility to a wide rangeof molecular sensing applications including: process andquality control, remote sensing, imaging, and spectroscopy.

experienced team, can help you.
