A chip-shaped laser medium ( 12 ) is side pumped to improve mode matching between the pumping energy ( 50 ) and lasing mode volume ( 36 ). The chip thickness ( 44 ) and laser medium doping level can be designed and controlled to ensure adequate pumping coupling efficiency. The chip shape can also be employed to provide greater chip surface areas ( 22 ) for cooling the laser medium ( 12 ). The laser pumping package ( 70 ), gain module ( 10 <SUB>1</SUB>), and chip-shaped design can be scalable to offer higher pumping power and high output power. Different orientations of the gain modules ( 10 <SUB>1</SUB>) with respect to each other can be used to provide better lasing mode quality.
