“…Owing to features such as excellent thermal conductivity, high mechanical durability, and wide amplification bandwidth, Ti:sapphire is widely used as a medium for high-power chirped pulse amplification (CPA) technology [1,2]. Some researchers from RAL, SIOM, PEARL, Apollon Project, and APRI, ELI, J-KAREN, and Vulcan have previously generated several petawatt (PW) laser pulses and are targeting 10 PW or more [3][4][5][6][7][8][9][10][11]. A high-power laser can be used in applications such as laser-material interaction, particle acceleration, basic research about materials under extreme environments, and medical applications [12][13][14].…”
