The impingement cooled laser apparatus including a laser rod (12) that is surrounded by an inner sleeve (24) and an outer sleeve (28). The space between the inner and outer sleeves (24, 28) forms a fluid channel. Coolant is introduced via input ports (32) and fills the fluid channel between the two sleeves. There are evenly distributed small jet holes (38) through the inner sleeve (24) to allow the coolant to spray through to the laser rod (12). After the coolant has impinged perpendicularly on the laser rod (12), it is drawn off through coolant outlet ports (36).
