A mounting improvement for the solid state laser bars used for example to
pump high power lasers is provided. Solid state laser bars are mounted in
side by side relationship and combined with integrated substrate and
laser output directing optical elements on a disclosed Integrated Diamond
Carrier. The Integrated Diamond Carrier is preferably fabricated as an
essentially freestanding base plate of diamond composition with
incorporated arrays of mesa structures providing mounting for the laser
bars and providing integral laser output directing optical elements such
as mirrored prisms. Integrated diamond carriers according to the
invention provide stable positioning, desirable thermal conductivity and
consistent low temperature operation for the solid state lasers.

We claim:
1. Laser diode array apparatus comprising: a sacrificial substrate member, of first material composition, having a generally planar upper working surface with an ordered array of
working surface indentations received therein; a first sub array of said sacrificial substrate working surface indentations comprising a plurality of parallel rows of elongated flat bottomed recessions extending across a substantial two dimensional
working surface portion; a second sub array of said sacrificial substrate working surface indentations comprising plurality of parallel rows of elongated sloping cross sectional recessions of greater depth and cross sectional area than said first array
indentations and of intermediate parallel location with respect to said first array indentations; each element in said second sub array of said sacrificial substrate working surface indentations including a sacrificial substrate member material crystal
plane determined laser energy reflection sur . . . . More |
