“…This figure suggests that the T laser might be one of the most promising laser at present stage as a high power light source to erase and write optical disk memory Another structure of a single stripe diode laser is an SBA(self-aligned bent active layer) schematically shown in Fig. 6 [5,6]. When cavity length and active region (2) Enlarging spot-size a.…”

“…4W under pulsed condition were experimentally obtáined (9,1O). In this paper, we describe our results to applying the idea to simple planar-stripeS lasers with stripe width of 15Om, which has gain-guiding mechanism on the contrary to SBA lasers (11,12). At the same time, we introduce a concept invented in CO2 laser field(13) into the diode laser field to reduce fringes.…”

Modal reflector having a high refIective(4O%) region with 24gm-, 48jm-or 96im-width on output facet applied for gain-guided wide(15Oirn) stripe lasers is described. Partially high reflective region composing the modal reflector consists of A1203/a-Si multi-layer whose thickness is determined so as to match in phase between a part of the output from the high reflective region and remaining output from the low reflective(---l%) region in order to reduce side peaks(fringes) in far--field patterns. As narrow single-lobed far-field pattern for lateral direction as 0. 88° ---3. 5° are observed up to 0. 4W under CW condition. Physical meaning of modal reflector is also discussed briefly.
