We　have　demonstrated　a　1　mu　m　fiber-solid-state　hybrid　high-energy　laser　in　the　hundred-picosecond　range.　Operating　at　a　repetition　rate　of　1　kHz,　the　output　energy　was　71.1　mJ　with　a　pulse　duration　of　63.8　ps.　By　simulating　and　analyzing　the　pumped　laser　intensity　inside　crystals　of　different　cross-section　diameters,　and　by　utilizing　the　spherical　aberration　self-compensation　effect,　the　positive　spherical　aberration　thermal　lens　of　the　crystal　could　be　reasonably　utilized　to　compensate　for　the　spherical　aberration　of　the　beam;　the　beam　quality　isM2x=2.10　andM2y=2.43.　This　high-energy　multi-stage　laser,　which　does　not　require　pumping　optical　coupling　or　insertion　of　additional　spherical　aberration　compensating　elements,　can　be　used　in　the　fields　of　non-linear　frequency　conversion　and　industrial　precision　machining.　(c)　2025　Optica　Publishing　Group.　All　rights,　including　for　text　and　data　mining(TDM),　Artificial　Intelligence　(AI)　training,　and　similar　technologies,　are　reserved.
