L12004-2209H-C Datasheet, PDF (3/8 Pages) Hamamatsu Corporation – Quantum Cascade Laser
IDFB-Pulsed Type
Quantum Cascade Lasers, using structures of SPC (Single Phonon-Continu-
um) depopulation and DFB (Distributed Feedback), emit pulsed mid-IR laser
under room temperature.
By controlling the chip's operating temperature through the Peltier element in-
stalled in the TO-8 package, it is possible to tune the emission wavelength
without mode hopping while keeping longitudinal single mode operation.

(*1) This specifies the temperature range within which the target emission wavenumber (K) can be realized. (*2) Full-width half maximum
(*3) This specifies the continuous tunable range (without mode hopping). The center wavenumber of the tuning range is the emission wavenumber (K).
(*4) The figures are limited by the resolution and signal/noise ratio of the measuring instruments used. (*5) K: Emission wavenumber (cm-1)

CLASS 3R LASER
Invisible Laser Radiation: Avoid Direct Exposure of eyes to Beam
GThe Laser emits invisible laser radiation.
The instrument which used the LASER, opera-
ted under ordinary conditions, is classified as
Class 3R according to the laser product classi-
fication code IEC 60825-1.
See IEC 60825-1 for more details and safety
operation concerning the above countermea-
sures.
