WebbInhomogeneous broadening can be caused in various ways: Different velocities of the atoms of a gas (e.g. in a gas laser) cause different Doppler shifts (→ Doppler broadening ). In a solid medium, there can be different lattice locations e.g. of laser … Webb15 juni 2004 · The effects of size fluctuation (inhomogeneous line broadening) and carrier relaxation on the modulation bandwidth of the laser are taken into account. Slow carrier relaxation from the excited-state to the ground-state limits the modulation bandwidth to ∼8 GHz even for high modal gain.

Webb15 okt. 1991 · The broadening of the Raman line in the frequency domain was found to be predominantly caused by the anharmonic decay of optical phonons into lower-energy acoustic phonons, resulting in a line broadening that is inversely proportional to the average isotopic mass m ¯. crazy craft the princessWebb1 maj 2024 · The modal peak gain of LD1 is larger than LD2, which can be explained by the smaller inhomogeneous broadening of LD1. The lines are linear fitting of the experimental data of mode peak gain, which gives the differential gain of the LDs. The differential gain of LD1 and LD2 are 3.53 and 2.08 cm/kA, respectively. crazy frog i like to move it youtube
