我们报告了单通差频产生的中红外飞秒脉冲可调谐范围在3.2-4.8 μ m的两个分支锁模掺铒光纤源。平均功率水平高达1.1毫瓦，在82 MHz的重复率，在中红外获得。这是通过在1.58 μ m的固定波长处的170 mW、65 fs泵浦脉冲与在1.05和1.18 μ m之间的近红外范围内可调谐的11.5 mW、40 fs脉冲的非线性混合来实现的。这些值指示可调谐近红外输入分量以量子效率被下变频。超过30%。(c)2007年，美国光学学会。
We report single-pass difference-frequency generation of mid-infrared feratosecond pulses tunable in the 3.2-4.8 mu m range from a two-branch mode-locked erbiura-doped fiber source. Average power levels of up to 1.1 mW at a repetition rate of 82 MHz are obtained in the mid infrared. This is achieved via nonlinear mixing of 170 mW, 65 fs pump pulses at a fixed wavelength of 1.58 mu m, with 11.5 raW, 40 fs pulses tunable in the near-infrared range between 1.05 and 1.18 mu m. These values indicate that the tunable near-infrared input component is downconverted with a quantum efficiency that. exceeds 30%. (c) 2007 Optical Society of America.
