Optimization of a multi-TW few-cycle 1.7-m source based on Type-I BBO dual-chirped optical parametric amplification
Lu Xu, Kotaro Nishimura, Yuxi Fu +3
This paper presents the optimization of a dual-chirped optical parametric amplification (DC-OPA) scheme for producing an ultrafast intense infrared (IR) pulse. By employing a total…
