The lengths of the ridge waveguide (RW) region and the tapered gain region of a 1060 nm tapered laser are optimized for better output performance of such lasers. When the total length of the cavity is kept at 3 mm, the length of the ridge RW region is set to 500, 750, and 1000 μm. When the output power is 2 W, the required input currents, slope efficiencies of power-current curves, electro-optical conversion efficiencies, output spectra, and far-field characteristics of the three lasers are compared. The results show that the output performance of the 1060 nm tapered laser is best when the length of the RW region is 750 μm and that of the tapered gain region is 2250 μm. Under an output power of 2 W, the required input current is 3.95 A, the slope efficiency is 0.61 W/A, and the conversion efficiency is 33.9%,the width (full wave at half maximum) of the spectrum is 0.3 nm, the far field is approximately Gaussian distribution, and the horizontal divergence angle is about 14° at energy of 95%.
