Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0024] like figure 1 As shown, a high-power tunable narrow-linewidth external cavity semiconductor laser includes: a gain chip 1, a tunable external cavity 2, a tilted power amplifier 3 with a curved waveguide; the gain chip 1, the tunable The external cavity 2 and the inclined power amplifier 3 with a curved waveguide constitute a complete optical system.
[0025] The gain chip 1 is used to generate a single-mode wide-spectrum light source. In order to realize narrow linewidth laser output, the ridge waveguide 4 of the gain chip must adopt a single-mode waveguide or an approximate single-mode waveguide. Therefore, the ridge waveguide 4 of the gain chip in the present invention adopts a narrow ridge semiconductor refractive index waveguide.
[0026] like figure 2 As shown, the tunable external cavity 2 functions to compress the intrinsic ...
