Quantum cascade laser (QCL)
QCL is a semiconductor laser with emission wavelength in the mid-IR range (4 um to 10 um). Because its emission principle is completely different from normal LDs, the QCL has gained attention as an lnnovative solution for mid-IR applications such as trace gas analysis in environmental monitoring.
|Peak emission wavelength typ.||4.33 μm|
|Tunable range min.||± 1.0 cm-1|
|Output power min.||20 mW|
|Lasing threshold current max.||1 A|
|Side-mode suppression ratio min.||25 dB|

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website.
