GaSb-basierende 2.3 µm Diodenlaser mit reduzierter Fernfelddivergenz
Abstract
There is an increasing interest in room-temperature diode lasers emitting in the infrared wavelength region between 2.0 and 2.5 pm for spectroscopic gas-sensing, medical diagnostics and therapy [1]. For all of these applications, fiber-coupled laser systems are desirable, which call for a laser design with low beam divergente and concomitant high output power.
