Abstract
A laser-diode pumped solid-state laser apparatus comprises at least one laser diode producing a pumping laser light, and at least one laser light generator including a monocrystalline substance doped with a dopant element and pumped with the pumping laser light from at least one laser diode, the monocrystalline substance containing the dopant element with a concentration profile such that the dopant element increases a concentration thereof in a direction perpendicular to a laser oscillation direction gently in the form of a slope from a near zero concentration.
