Dont do h or g. 2 3 Laser Properties Verdeyen 9.4 4 Mode-Locking The Nd:YAG has a gain bandwidth of 1 . 2 10 11 Hz (FWHM). A particular mode-locked Nd:YAG laser generates 50 nJ pulses. (a) Give an esimate of the shortest pulse that can be generated with an Nd:YAG gain medium. (b) Assuming the pulses are as short as possible, give an estimate of the peak power. (c) The end mirrors of the laser are 1.0 m apart and the laser is modelocked. How often does the laser emit a pulse? (d) What is the average power? (e) How many longitudinal modes are mode-locked together? Assume the full bandwith is 2.5 times the FWHM. 3...
