概要 |
The development of a widely tunable coherent mid-infrared optical source,which can be used for various types of trace-gas sensing, is reported.This source utilizes difference frequency generation (DFG...) in a periodica11y poled LiNbO3(PPLN)crystal pumped by two single-frequency diode lasers. Wide range tunable output in the range 3.7 to 4.8 μm is achieved by tuning one of the diode laser and altering the temperature of the single-period PPLN.Development of a fiber-coupled,tunable Cr3+:LiSrAlF6 1aser,which can be used for the DFG process is also described.In addition,preliminary studies regarding an application of the gas sensor for absorption measurements of ambient CO2 gas is reported.続きを見る
