Room temperature high power mid-IR diode laser bars for atmospheric sensing applications

Diode lasers: From laboratory to industry

“…The 2100 nm laser emission obtained from Holmium doped YAG crystals pumped by 1900 nm LD are attractive for free-space communication and range-finding applications due to little absorption in atmosphere at this wavelength. The 2100 nm LD sources can eliminate the need of these solid state laser systems at significant cost saving [45]. Diode lasers based instruments have also been employed as probable detectors in warfare agents related researches and studies.…”
