During　the　grinding　process,　K9　optical　glass　exhibits　poor　machinability,　leading　to　issues　such　as　crack　growth,　machining　costs,　low　machining　efficiency,　and　many　other　problems,　seriously　restricting　its　manufacture　and　application.　This　paper　evaluated　the　feasibility　of　picosecond　laser-assisted　polishing　of　optical　glass　workpieces　as　an　economical　production　method.　This　study　involves　a　comprehensive　exploration　of　several　key　aspects,　including　workpiece　dimension　control,　the　surface　quality　after　picosecond　laser　ablation　assessment,　the　parameters　of　the　picosecond　laser　equipment　optimization,　and　fine-tuning　the　parameters　of　the　polishing　equipment.　The　results　show　that　the　workpiece　surface　exhibits　a　recast　layer　with　an　uneven　thickness　distribution　after　laser　processing,　leading　to　a　38%　reduction　in　luminous　flux.　Additionally,　the　roughness　of　the　ablated　surface　decreases　as　the　pulse　repetition　rates　increase　from　40　to　120　kHz.　Due　to　the　nonlinear　absorption　of　energy　by　the　amorphous　body,　the　maximum　ablation　depth　occurs　around　80　kHz.　Furthermore,　the　unevenly　distributed　recast　layer　affects　the　polishing　process.　Nevertheless,　the　efficiency　of　the　picosecond　laser-assisted　polishing　method　is　greatly　improved　compared　to　the　conventional　method　of　precision　grinding　followed　by　polishing.　©　The　Author(s),　under　exclusive　licence　to　Springer-Verlag　London　Ltd.,　part　of　Springer　Nature　2024.
