✦ Synopsis

An efficient control technique that allows obtaining coatings with optimal thickness, i.e., minimal residual reflecti¨ities on the semiconductor laser amplifiers facets, is described. The technique consists of completing the antireflection coating e¨aporation on the laser facets when the ripple on the amplified spontaneous emission spectrum presents the possible lowest ¨alue.
