We report on the development of high-power laser diodes and laser bars emitting in the visible red spectral region.
High power diode laser bars require thermal management packages with high cooling efficiencies and long-term stability.
With optimized layer structures 5-mm wide laser bars at 650 nm with a maximal output power of 55 W in pulsed operation were realized.
The design is based on a linear array of 7 laser bars and beam forming optics featuring a micro-optic homogenizer.
Based on Snell's law and the constant phase in the front of optical field, a design method of the slow axis collimation lens with variable curvature radius is proposed for semiconductor laser bars.
The method for designing the waveguide structure can efficiently increase the loss of high order modes, lower the threshold current, improve the output power and far-field characteristics, which is applied to any kind of edge emitting lasers or laser bars.
