- A mode-locked laser has a linewidth of 100nm at a center wavelength 1050nm. Assume the pulse shape is hyberbolic secant and it is transform limited. What is the pulse width (in fs)? (round all answers to 1 sig. fig. after decimal point) a.116.0 b.11.6 c.5.8 d.58.0 e.100.0Suppose you measured a spectrum of a laser source which peaks at a wavelength of 810 nm. Find the energy (in eV) associated with this wavelength. From the LED spectrum data you want to find the width of the peak at half the height of the peak. The wavelengths at which the intensity is half of its peak value are 630 nm and 666 nm respectively. Using these wavelengths determine the width of the peak in units of energy (eV). From the N2 spectrum data you noted two prominent peaks at wavelengths 330 nm and 350 nm. Determine the energy associated with each peak. The larger energy represents the energy difference between the vibrational ground states of two molecular orbitals (denoted by C’IIu and B³IIL). The smaller one represents the energy difference between the vibrational ground state of the C'II, orbital and first excited vibrational state of B³II.. The difference between these energies represents the energy difference between the ground and first excited vibrational levels. Find this…Quartz is a uniaxial birefringent material with refractive indices no=1.5534 and ne=1.5443.
