TUNABLE INFRARED LASERS FOR GAS-PHASE SPECTROSCOPY |
摘要 |
Exemplary embodiments provide tunable laser devices, methods for making the laser devices and methods for tuning the laser devices. The tunable laser devices can include an optically pumped semiconductor laser heterostructure, on which a distributed-feedback (DFB) laser grating having variable grating spacings (or chirps) can be formed. The optically pumped semiconductor laser heterostructure can be an optically pumped type-II quantum well laser structure. The emission wavelength of the tunable laser devices can be tuned by changing positions of the region illuminated by the pump laser and with respect to the chirped DFB grating. The disclosed laser devices and methods can provide tunable laser emission with a combination of narrow linewidth and high output power that can be used for remote sensing applications and/or spectroscopic applications across the entire mid infrared (IR) spectral region.
