High rep-rate, high peak power 1450 nm laser source based on optical parametric chirped pulse amplification [Early Posting]
We present a high peak power near-infrared laser system based on optical parametric chirped pulse amplification pumped by a home-built picosecond pumping laser, which can generate over 40 mJ energy at 1450 nm center wavelength and operate at 100 Hz repetition rate. Subsequently, the chirped laser pulses are compressed down to 60 fs with 26.5 mJ energy, corresponding to the peak power of 0.44 TW. This high energy and long wavelength laser source is well suitable for driving various nonlinear optical phenomena such as high harmonic generation and high-flux coherent extreme ultraviolet/soft X-ray radiation.
