Answer:
the fractional loss per pass =0.053
the decay time of the cavity =11 ns
Explanation:
laser is an acronym for Light Amplification by Stimulated Emission of Radiation and it has lot of military applications : basically ranging from target acquisition, fire control, and training. It is also being used in LIDAR communications, radar systems , laser guided landing systems, laser pointers, holography, photography, guidance systems, scanning machines, metal working, and medicine.
the fractional loss per pass= [tex]\alpha l - ln(R_1R_2)^ \frac {1}{2}[/tex]
but no excited state absorption, therefore [tex]\alpha[/tex] is 0
[tex]= - ln(R_1R_2)^ \frac {1}{2}\\\\=- ln(0.999* 0.9)^ \frac {1}{2}[/tex]
=0.053
b) the decay time of the cavity:
[tex]T_c = \frac{nd}{cl_f}=\frac{1,76 * 10 *10^-2}{3 *10^8 *0.53}[/tex]
=1.1 *10^-8 seconds
=11 ns
