WTB: portable YAG laser

I'm looking to get a portable YAG laser operating in pulsed mode (class IV) and equipped with internal batteries for a reasonable price. BTW this laser should not be derived from US American model of SSY-1 for obvious reasons. Basically I want a handheld battery powered laser (1064 nm) that is capable of doing some decent burning and putting holes in stuff, possibly housed in a decent case. Just to be clear I want this device for pure hobby, and also to do some tests and demonstrations with it. This device will NOT be used as a “not-conventional weapon” or other similar purposes
