Diode laser-pumped solid-state lasers

“…Sipes took advantage of the recently introduced commercial diode laser arrays invented and developed. at Xerox by Scifres, Burnham, and Streifer (17) and commercializcd in a joint venture between Xerox and Spectra Physics. The early multistripe diode laser arrays introduced by Spectra Diode were capable of producing in excess of 0.1 W of continuous wave output at 35% electrical to optical efficiency.…”

Linear tailored gain broad area semiconductor lasers

“…As the guide width P is increased, the endpoint z = p + UP penetrates deeper into the Stokes region I L z I < r / 3 and the increasing ratio a / b reflects the growing dissimilarity between Ai ( z ) and Bi (2). Only when the endpoint z = p + we lies near the Stokes line at L z = T / 3 does Bi ( z ) make a significant contribution to the eigenmode.…”

“…Below the negative real axis, the + exponential provides the dominant contribution to Ai (2). The radicals may be simplified by making a binomial expansion about u = 0 with v << u :…”

“…Although the array structure solves the filamentation problem by confining the filaments to individual laser channels, the lateral mode problem remains. The well-known undesirable twin-lobed far-field pattern of a uniformly spaced array of identical lasers [2]- [4] comes about because the lossy interchannel regions in the uniform array cause the highest order supermode to have the highest modal gain, and this mode has a twin-lobed far-field pattern [5], [6]. In principle, one method of achieving fundamental mode operation in an array would be to vary (e.g., chirp) the widths of the array elements so that the fundamental mode is localized in a different spatial region than the higher order modes [7].…”
