Abstract

High power diode lasers with low modal gain (~4 cm-1), predicted to operate with very low filamentation, are shown to operate with near-field modulation depth half that of reference devices (~12 cm-1). However, beam quality is unaffected.

差分模态增益对广域二极管激光器丝状特性的影响

具有低模态增益(~4 cm-1)的高功率二极管激光器，预计在非常低的灯丝下工作，显示出近场调制深度是参考器件(~12 cm-1)的一半。但是，光束质量不受影响。
