1 Quantum Cascade Laser Front: QCLs Back: Set-up examples with exclusive accessories Quantum Cascade Lasers are semiconductor lasers that offer peak emission in the mid-ir range (4 µm to 10 µm). They have gained considerable attention as a new light source for mid-ir applications such as molecular gas analysis. Features Applications Mid-IR laser (4 µm to 10 µm) Compact, lightweight Trace gas analysis Environmental measurement, Combustion gas measurement, Plasma measurement, In vivo gas analysis IR molecular spectroscopy Chemical sensing, Molecular oscillation

2 QCL LINEUP CW Quantum Cascade Lasers Quantum Cascade Lasers, which emit single mode mid-ir laser beam under the room temperature by employing Single Phonon Resonance-Continuum Depopulation (SPC) and Distributed Feedback (DFB) structures. By controlling the chip's operating temperature through the Peltier element installed in the HHL package, it is possible to tune the emission wavelength without mode hopping while keeping longitudinal single mode operation.

16 Read carefully before using QCL For safe and effective use, carefully read the documents that come with your QCL and accessories. Read all manuals and instructions thoroughly and also be aware of local laser rules and regulations.! Warning This catalog is not a guarantee of product perfection. When the products are used in an instrument which may cause bodily harm or damage property, it is dangerous to operate the instrument unless proper safety measures are taken against possible product defects.! Caution Absolute maximum ratings Absolute maximum ratings listed in the specification sheet and/or test sheet are limiting values that must not be exceeded even momentarily. Using this product under conditions where any one of the maximum ratings is exceeded may cause serious and irreparable damage to the products. Values in absolute maximum ratings for forward current and forward voltage differ in each product, so always check the values listed in the test sheet that comes with each product and make sure that these values are not exceeded. Laser driver power supply Current surges and current fluctuations may impair performance of the laser device. Do not apply reverse current and reverse voltage to the QCL. Heat dissipation This product uses a Peltier element to control temperature of the laser device, so the Joule heat generated in this product must be dissipated. If operated with poor heat dissipation, the device temperature may soon exceed the absolute maximum rating for the operating case temperature listed in specification sheet. Make sure that a proper heatsink is installed on the product. Poor heat dissipation may lead to excessive heating during operation and cause device deterioration or opencircuit faults even if the Peltier current is within the maximum rating. Heat dissipation on the laser side may not be sufficient when supplying electrical current to the Peltier element in heating mode, and cause failures or affect reliability. Carefully check these points before actual operation. HAMAMATSU PHOTONICS K.K.
