Single-mode ridge waveguide semiconductor lasers based on AlGaAs/GaAs/InGaAs heterostructure with a surface distributed Bragg reflector were developed. Calculation of reflection spectrum based on coupled mode theory was carried out. Waveguide ridge with width of 5 mkm and Bragg grating with a period of 2 mkm was formed in the upper cladding layer by contact photolithography. Experimental studies shown that spectrum width did not exceed 0.3 nm both at continuous wave and pulse of 100 ns pump. Temperature stability of emission wavelength increased up to 0.075 nm/C.
