ABSTRACT:
Nonmonolithic laser arrays having a plurality of lasing elements mounted on protruding members of a stacked support which includes spacers between the protruding members. The protruding members and spacers are comprised of thermally conductive, but electrically insulative material such as BeO. The conductive layers on the spacers and protruding members assist in providing electrical contact to the lasing elements. The stacked support accurately locates and separates the lasing elements and enables low thermal and electrical crosstalk between the lasing elements.
