No full textThe parameters of a 0.81-mu m ridge heterolaser are optimised by using the procedure developed earlier. As a result, 200 mW of the single-mode output is obtained in a diffraction-limited beam. It is shown experimentally that the near-field two-dimensional intensity distribution of the lasers under study can be well represented in the factorised form, which demonstrates the applicability of the 'effective' refractive index method for simulating these lasers
