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 摻釹鈣鈮鎵石榴石(簡(jiǎn)稱(chēng)nd : cngg )是一種新型激光晶體,該晶體熔點(diǎn)低( 1470 ) ,具有無(wú)序結(jié)構(gòu),在通用的808nm半導(dǎo)體激光二極管( ld )發(fā)射波長(zhǎng)區(qū)有寬吸收帶,因此很適合ld泵浦,可做成ld泵浦全固態(tài)激光器。
