Abstract
A mode-locked gallium arsenide crystal laser has a cavity length equal to one-half its principal noise resonance wavelength and an electrode overlying a portion of the crystal, the remaining portion being a self-aligned region diffused or implanted with impurities comprising saturable absorbing centers. An anti-reflective coating is placed on a crystal facet facing an external mirror defining one end of the laser cavity. The resulting laser has improved power, frequency and temporal stability.
