An　acousto-optic　Q-switching　Ho:YLF　ring　oscillator　at　2066.33　nm　with　two　anti-misalignment　corner　cube　reflectors　(CCRs)　pumped　by　a　1940　nm　thulium-doped　fiber　laser　is　demonstrated.　The　depolarization　effect　of　the　CCR　is　expressed　in　the　form　of　equivalent　transmission,　and　the　transmission　from　two　output　directions　of　the　oscillator　is　changing　synchronously　and　periodically　as　the　waveplate　angle　changes.　In　the　experiment,　under　the　pump　power　of　21.76　W,　the　optimum　bidirectional　energy　of　3.13　mJ　for　a　pulse　duration　of　122　ns　at　a　repetition　rate　of　50　Hz　is　realized.　The　pulse　energy　reduction　percentage　at　50　Hz　is　8%　by　changing　the　horizontal　drift　angle　of　one　of　the　CCRs　to　4.5°.　The　beam　quality　factor　M2　is　calculated　to　be　about　1.10,　revealing　that　the　Ho　laser　is　working　in　a　fundamental　transverse　mode.　©　2023　by　the　authors.
