| 1. | It has a broader absorption band at 808 nm which is emitted by laser diode ( ld ) . therefore , nd : cngg is suitable for ld pumping , the ld pumped all solid - state lasers can be made by using nd : cngg . in this study , nd : cngg single crystals of 25mm in diameter and above 80mm in length were successfully grown by the automatically pulling method from the melt 掺钕钙铌镓石榴石(简称nd : cngg )是一种新型激光晶体,该晶体熔点低( 1470 ) ,具有无序结构,在通用的808nm半导体激光二极管( ld )发射波长区有宽吸收带,因此很适合ld泵浦,可做成ld泵浦全固态激光器。 |
