Apparatus and method for designing and operating a solid-state laser that compensates for thermal lensing such that lasing instability is maintained at high pumping power. In some embodiments, the laser is an optically pumped semiconductor laser (OPSL). In some embodiments, a concave end facet is formed on the OPSL that at least compensates for thermal lensing at high pump power. In some embodiments, an external mirror is used for at least one end of the OPSL, wherein the external mirror at least compensates for thermal lensing at high pump power.
