Abstract

A monolithic solid-state laser device is disclosed. The laser device is side pumped with a diode laser (32) and reflects the laser beam (29) from one face (21) of the solid state gain medium (22) to ensure gain uniformity. The solid state gain medium (22), output coupler (30) and back reflector (26) are integrally formed so that the resulting monolithic laser design provides a compact, rugged and self-contained laser device.
