A Nd: YAG Laser with a length of 0.01m is coated on both sides so that R=0.95
wavelength= 1.0?m
the linewidth of the laser transition is v = 10/cm
Absorption coefficient a=0.01/cm
Lifetime of upper laser level l = 3ms
refractive index n = 1.77
A. What is the minimum invertsion population requirement for lasing?
B. What is the Q of the Cavity?
