Well the filter passes the lasing weavelenth so we cant much damage that.
The lens is to focus the beam and is tranparent so we didnt damage that.
Mirror........ !@#%$#@!!
thats the puppy. It only passes the required weavlenth in one direction. The output side of the mirror is what you damaged and in some DPSS lasers these can be replaced cheap.
