摘要
采用体布拉格光栅(VBG)外腔来压窄并稳定二极管激光阵列(DLA)输出光束的频谱。实验结果表明:在VBG波长锁定前后,DLA输出光束的光谱宽度由1.7 nm减小到0.4 nm,压窄的光谱不随注入电流的增大发生明显变化,不随热沉的温度升高而明显漂移。VBG波长锁定后在注入电流为35 A时,输出功率为15.12 W,功率损耗约2%。
Stabilization and spectrum narrowing of the emission wavelength of high-power diode laser array is demonstrated by a volume Bragg grating （VBG） resonator. The spectral full width half maximum of the output emission was suppressed by VBG cavity from 1.7 nm to 0.4 nm, and the emission wavelength of VBG-locked diode laser array varied slightly with variation of output power and heat sink temperature. Output power of 15.12 W is achieved from VBC,-locked diode laser array with a loss of approximately 2% when the injection current is 35 A.
