Quantum Cascade Lasers, using structures of SPC (Single Phonon-Continu-

um) 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 in-

stalled in the HHL package, it is possible to tune the emission wavelength

without mode hopping while keeping longitudinal single mode operation.

CLASS 3B LASER

Invisible Laser Radiation: Avoid Exposure to Beam

GThe Laser emits invisible laser radiation.

The instrument which used the LASER, opera-

ted under ordinary conditions, is classified as

Class 3B according to the laser product classi-

fication code IEC 60825-1.

See IEC 60825-1, -14 for more details and

safety operation concerning the above counter-

measures.

(*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.
