recommendation for 532nm module 10-20mw for minimum 30min duty cycle

[milantheone]

hi guys i am in need for 532nm laser module that can be run for longer period of time. idealy i need just smalest possible module that i can place in heatsink of mine with apropriate airflow in mind.

i wonder if you can recommen me some??
there is a lot on ebay and ali, but i doubt those small modules can be run for prolonged time without shifting, hopping, be stable basicaly.

are there som good modules, or everything is just the matter of cooling??
