US 6,341,138 B1 · Constant temperature performance laser

Abstract

Diode lasers are fabricated whose performance is essentially unchanged over designed temperature and bias ranges. The threshold current (Ith) and the external efficiency (ηext) of the diode lasers are unchanged over a range of specified temperatures.
