1. A laser package comprising:
a bottom anode cooler having (i) a top surface, (ii) a bottom surface opposite the top surface, (iii) an entry recess defined in the bottom surface, (iv) a top recess defined in the top surface, and (v) fluidly connecting the entry recess and the top recess, a plurality of hollow ports for forming jets of cooling fluid therethrough, wherein the top surface of the bottom anode cooler comprises (a) a first portion surrounding the top recess, and (b) a second portion extending toward a rear side of the bottom anode cooler; and
disposed above the bottom anode cooler, a top anode cooler having (i) a top surface and (ii) a bottom surface opposite the top surface, the bottom surface comprising an impingement surface and an outer border surrounding the impingement surface, wherein (a) the outer border is coupled to the first portion of the bottom anode cooler, and (b) the top anode cooler does not overlie the second portion of the top surface of the bottom anode cooler,
wherein (i) the impingement surface defines a non-planar pattern, whereby cooling fluid introduced into the bottom anode cooler and jetted through the ports strikes the impingement surface of the top anode cooler, and (ii) the top surface of the bottom anode cooler defines a front depression extending from the first portion to a front side of the bottom anode cooler and recessed below the first portion.
