We report on a new periodically poled lithium niobate grating design with a continuous grating-period change (fan-out). We observed 350cm(-1) (80 nm at 1.5microm) of complete spectral coverage at a constant temperature in a cw optical parametric oscillator. Complete spectral coverage is demonstrated by measurement of an absorption band of CO(2) .
我们报道了一种新型的周期性极化铌酸锂光栅设计，其具有连续的光栅周期变化（扇出）。我们在连续波光参量振荡器中，于恒定温度下观测到了350厘米⁻¹（在1.5微米波长处为80纳米）的完整光谱覆盖范围。通过测量二氧化碳的吸收带证实了完整的光谱覆盖。
