Amplification of chirped pulses. Diagram
Chirped pulse amplification ( CPA ) amplification - the technique of amplifying ultrashort laser pulses up to a petawatt power level by stretching a broadband pulse in a dispersive optical system (usually a pair of prisms ) before amplification and subsequent compression of the pulse after amplification by an optical system with reverse dispersion (for heavy-duty pulses, only diffraction gratings and, possibly, mirrors can be used as such a system). CPA is currently the main technique for producing pulses of the highest power.
Amplification of chirped pulses was first proposed in 1985 by Gerard Muru [1] and Donna Strickland . On October 2, 2018, they received the Nobel Prize in Physics for this technology. [2]
