Theoretical investigation of amplified spontaneous emission in an active structure by extended (3×3)transfer matrix formalism: the case of a non-uniform longitudinal distribution of emitters [PDF]
Journal of the European Optical Society-Rapid Publications, 2006 We use an extended (3×3) Transfer Matrix Formalism (TMF) to investigate the properties of Amplified Spontaneous Emission (ASE) in an active structure that exhibits a non-uniform spatial distribution of emitters along its longitudinal axis.

Purely Gain-Coupled Distributed-Feedback Bragg Semiconductor Laser Diode Emitting at 770 nm
Applied Sciences, 2021 The transition lines of Mg, K, Fe, Ni, and other atoms lie near 770 nm, therefore, this spectral region is important for helioseismology, solar atmospheric studies, the pumping of atomic clocks, and laser gyroscopes.
