L12004-2209H-C Datasheet, PDF (2/8 Pages) Hamamatsu Corporation – Quantum Cascade Laser

QCL LINEUP
IDFB-CW Type
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.

(*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)
I Limited quantities of QCLs with emission wavelengths close to those specified above may be available occasionally.
