Apart from oppositions, are there any other ways to challenge a patent in Laos?

After the 90-day opposition period post publication, any interested party may need to wait until the grant of patent and/or petit patent to file a cancellation/invalidation action. A third-party observation is not available in Laos like some other countries.
