“…In particular, petawatt laser systems also were demonstrated in some large laboratories, for example, 1.5 PW in 440 fs hybrid Ti:sapphire -Nd:glass laser system was developed in LLNL [2], 1.1 PW hybrid OPCPA (optical parametrical CPA) Nd:glass laser was developed in Texas [3], and 0.85 PW in 33 fs Ti: sapphire laser system was developed in Japan [4]. However, these petawatt-class laser facilities work at very low repetition rate which is limited of few-shot per hour or single shot.…”

“…OPCPA has been applied and becomes promising for constructing high-intensity lasers [5][6][7][8][9], particularly with the invention of new nonlinear crystals such as YCOB (YCa 4 O(BO 3 ) 3 , YCOB) [10][11][12]. Compared with other nonlinear crystals commonly utilized in OPCPA systems, YCOB crystal has several prominent properties: high damage threshold, moderate thermal conductivity, and nonlinear coupling [13].…”

We report a novel ultrabroadband high-energy femtosecond laser to be built in our laboratory. A 7-femtosecond pulse is firstly stretched by an eight-pass offner stretcher with a chirp rate 15 ps/nm, and then energy-amplified by a two-stage optical parametric chirped pulse amplification (OPCPA). The first stage as preamplification with three pieces of BBO crystals provides the majority of the energy gain. At the second stage, a YCOB crystal with the aperture of ~50 mm is used instead of the KDP crystal as the gain medium to ensure the shortest pulse. After the completion, the laser will deliver about 8 J with pulse duration of about 10 femtoseconds, which should be beneficial to the attosecond pulse generation and other ultrafast experiments.

“…Peak power up to multiterawatt(10 12 W, TW) based on CPA Ti:sapphire laser has been widely realized by many groups over the world. In particular, petawatt(10 15 W, PW) laser systems were also demonstrated in some large laboratories, for example, 1.5 PW in a 440 fs hybrid Ti:sapphire-Nd:glass laser system was developed in LLNL, [2] 1.1 PW hybrid OPCPA (optical parametrical CPA) Nd:glass laser was developed in Texas, [3] and 0.85 PW in a 33 fs Ti:sapphire laser system was developed in Japan, [4] and high contrast 1.16 PW with a combination of Ti:sapphire laser and OPA was demonstrated in our group. [5] However, these petawatt-class laser facilities work at very low repetition rate, which is limited to few shots per hour or single shot.…”
