Quantum Cascade Lasers.. A wide range of industries, including biomedical, defense, and sensing, utilize tunable mid-infrared lasers that, until recently, have required some rather exotic system configurations.. These have historically ranged from free-electron lasers, which require a particle accelerator, to multistage Raman shifted alexandrite ..
These Quantum Cascade Lasers have a minimum average power of 1W and more than 9W of peak power.. Available in a collimated HHL package with a dedicated driver, these lasers can be used for free-space optical communications, energy deposition, illumination and IR countermeasures.. Broad Gain lasers..
The light vs.. driving current (L-I) curves measured for quantum and interband cascade Lasers (QCLs and ICLs) include a rollover region, which is enclosed by the red box in Figure 1.. The rollover region includes the peak output power of the laser, which corresponds to a driving current of just under 500 mA in this example..

Quantum Cascade Lasers (QCLs) are a perfectly suited solution to build such analysis systems.. Until now, QCLs only covered the wavelength range from 4 to 10µm, where many chemical species are detected (NO, N2O, NH3, CH4, COH2, CO, CO2, SO3, etc..).. However, the fingerprint region extends much farther in the infrared, and current laser ..
