Hamamatsu L12004-2209H-C Quantum cascade laser Datasheet

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.
●Mid-IR laser (4 µm to 10 µm) ●Compact, lightweight
Features
Applications ●Trace gas analysis Environmental measurement, Combustion gas measurement, Plasma measurement, In vivo gas analysis
●IR molecular spectroscopy Chemical sensing, Molecular oscillation
QCL LINEUP
■DFB-CW Type
Quantum Cascade Lasers, using structures of SPC (Single Phonon-Continuum) depopulation and DFB (Distributed Feedback), emit CW (Continuous
Wave) mid-IR laser under room temperature.
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.

■Heatseeker A10767
Heatseeker A10767 consists of 2 types of thermal viewing card and an alignment target. It can
be used for visualization and alignment of the QCL laser beam.
Thermal Viewing Card
Thermal material provides visibility of the IR laser beam. Facilitates tracing of the invisible laser
beam. Two cards with different sensitivity ranges are provided.
Alignment Target
The light axis of the invisible IR laser beam can be easily aligned. Includes a cross target for
checking the light axis. Thermal viewing card can be inserted.

Read carefully before using QCL
For safe and effective use of a QCL, carefully read the documents that came with the purchased goods.
Also, read carefully to the end of manuals and instructions, and observe the local law regulations about using lasers.
! 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 properties, 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 open-circuit 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.
