Some Numerical problem

[@brijeshmehra8182]

REGARDING Q3,
A pulse repetition rate is the number of pulses emitted per second.
So, it is equal to del nu.
What sir has computed is repetition time. Isn't he?

[@parvezakhtar1053]

Sir is Q6 correct ??

[@MehulJotshi]

Yes. At the end, I get the expression, Lambda(pump)/Lambda(laser) = 940/1030 i.e. .912 W or 912 mW

[@RiazHussain-vi8ut]

Where is question 8

[@ARCSTREAMS]

wrong the pump lambda is 940nm not 1030nm you plugged the wrong numbers in the equation

[@Rahul-yg5kp]

sir is q6 correct

[@ARCSTREAMS]

you writting to small,you have enough room to write bigger
