Cr3+:LiSAF6(掺铬氟化铝锶锂)是一种继钛宝石之后新的优秀可调谐激光晶体.激光上能级寿命(67μs)比钛宝石(3μs)长,有适当高的发射截面(π偏振辐射截面达5×10-20cm2)、发射谱在700~1100nm处,有低的非线性折射率效应和热透镜效应小的优点.90年代,Cr3+:LiSAF6飞
Cr3 +: LiSAF6 (dichroic chromium-aluminum-fluoride-strontium lithium) is a new excellent tunable laser crystal following the titanium. The laser lifetime (67μs) is longer than that of titanium (3μs) and has a suitably high emission cross section (π-polarized radiation cross section of 5 × 10-20cm2) with an emission spectrum at 700-1100nm and a low nonlinear refractive index The advantages of small thermal effect and thermal lens. 90s, Cr3 +: LiSAF6 fly
