Upconversion of optical signals with multi-longitudinal-mode pump lasers

open access: yes, 2012
Multi-longitudinal-mode lasers have been believed to be good candidates as pump sources for optical frequency conversion. However, we present a semi-classical model for frequency conversion of optical signals with a multimode pump laser, which shows that
