1. The problem statement, all variables and given/known data Calculate the Q value for a krypton laser with λ=0.569 microns, 0.568m cavity and mirror reflectance of 100% for the rear and 52% for the output window. 2. Relevant equations For a laser cavity=> Q=(4πL)/(λ(1-R1*R2)) 3. The attempt at a solution Q= (4*π* 0.568m)/((0.569x10^-6)(1-(1)(0.52)) = 2.61x10^7 m I am not sure if this is correct, can the Q factor be this high? Thanks for your help!
