The simulation of a twelve pulse diode rectifier with saturable reactors [PDF]

open access: yes, 2004
A twelve pulse diode rectifier with saturable reactors to allow a degree of phase control is simulated using mathematical software. First order differential equations are solved numerically to allow calculation of line current.

Chirped pulse Raman amplification in plasma: high gain measurements [PDF]

open access: yes, 2009
High power short pulse lasers are usually based on chirped pulse amplification (CPA), where a frequency chirped and temporarily stretched ``seed'' pulse is amplified by a broad-bandwidth solid state medium, which is usually pumped by a monochromatic ...

Chirped pulse Raman amplification in plasma [PDF]

open access: yes, 2011
Raman amplification in plasma has been proposed to be a promising method of amplifying short radiation pulses. Here, we investigate chirped pulse Raman amplification (CPRA) where the pump pulse is chirped and leads to spatiotemporal distributed gain ...
