Cheap green 532 nm laser pointers are frequency-doubled 1064 nm (Nd:YVO₄) lasers, and some leak invisible infrared (808 nm diode pump light and 1064 nm) alongside the green.

The joke: Only laser people know the pointer is a nonlinear crystal and a safety hazard. The slogan on the mug reads GREEN POINTER. INVISIBLE 1064 TOO.
