6. A laser diode package comprising:
a laser diode having a longitudinal axis;
a first pyrolytic graphite (PG) substrate body having a diode mounting surface on which the laser diode is mounted such that the longitudinal axis is substantially parallel with the diode mounting surface, and having a PG crystalline structure with a basal plane substantially non-orthogonal to the diode mounting surface so that a coefficient of thermal expansion (CTE) of the first PG substrate body is substantially matched with a CTE of the laser diode; and
a second PG substrate body connected to the first substrate body opposite the diode mounting surface of the first substrate body, said second substrate body having a PG crystalline structure with a basal plane substantially non-orthogonal to the plane of the diode mounting surface.
