Switch Yag
duty cycle, peak power per pulse and energy of an impulse?
Please help me find the solution to this problem. The answer Coming after the question of the output of a cw laser pumping Nd: YAG Q-switch at a pulse repetition frequency of 10 kHz. If each pulse is 50 ns wide and if average output power is 10 W, calculate a. duty cycle [5 x 10-4] b. maximum power per pulse [2 x 104 W] C. the energy of a pulse [0.001 J]
The duty cycle is the fraction of time the light is on. You said that the pulse is 50 ns wide. The period between pulses is the inverse of the frequency: 1 / (10 kHz) = 10 ^ -4 seconds. The light is on for 50 * 10 ^ -9 sec to 10 ^ -4 seconds, or 50 * 10 ^ -9/10 ^ -4 = 5 * 10 ^ -4 Peak power is the power required to give an average power of 10W if the light is only for the duty cycle 5 * 10 ^ – 4 of the time. Paverage ppeak = / cycle service you can do algebra. The energy of a pulse is the time to peak power, time is on, which is 50 ns.

The Living Fire (E Zhivindi Yag) $15.28 Ronald Lee’’s autobiographical novel, formerly published as Goddam Gypsy, is an intense, fast moving, and brutally honest affair. Yanko–a Canadian Rom who ”took the non-Romani way but didn”t go far”–seeks his fortunes both among and apart from the Roma, never quite finding his place. His story exposes the out of sight, out of mind world of Canada’’s Roma in 1970′’s Montreal: Parties, rackets, bar brawls, weddings, desperate poverty, and intermittent police raids fuel in Yanko the passion, creativity, and rebellious defiance that is The Living Fire. |
