Abstract：

We　have　developed　a　diode　side　pumped　intracavity　frequency　switched　Nd:YAG　laser　with　fiber　coupled　output,　which　has　the　characteristics　of　high　power,　high　beam　quality　and　high　brightness,　and　has　a　unique　application　in　the　field　of　laser　processing.　In　order　to　solve　the　influence　of　thermal　effect　of　Nd:YAG　crystal　on　optical　resonator,　the　thermal　focal　length　was　measured　and　a　stable　cavity　structure　was　designed.　When　the　repetition　rate　was　10　kHz,　the　maximum　output　power　of　the　532　nm　laser　was　96　W,　and　the　pulse　width　was　55.8　ns.　The　beam　quality　was　measured　as　Mx2=　5.98　in　the　horizontal　direction　and　My2=　8.14　in　the　vertical　direction,　corresponding　to　the　brightness　of　6.97×108　W·cm−2·Sr.　The　maximum　fiber　coupling　output　power　was　94　W,　with　a　fiber　core　of　200　μm　and　a　fiber　coupling　efficiency　of　98　%.　As　far　as　we　know,　the　fiber–solid-state　acousto-optic　Q-switched　532　nm　laser　obtains　the　highest　brightness.　©　2024　The　Authors
