A laser apparatus for producing a laser light beam can include a gain
medium; a pump light source to provide a pump light beam to the gain
medium; a first reflector disposed between the first gain medium and the
first pump light source and spaced apart from a gain portion of the first
gain medium; a second reflector; and an output coupler. The first
reflector is substantially reflective to the laser light beam and
substantially transmissive to the pump light beam. The first and second
reflectors and the output coupler define a folded beam path having a
first portion and a second portion. The first portion of the beam path
extends from the first reflector to the second reflector through the gain
medium and the second portion of the beam path extends from the first
reflector to the output coupler through the gain medium. The first and
second beam paths define, within the gain medium, a non-zero folding
angle. Optionally, the laser apparatus can include a second pump light
source that can pump the same, or a second, gain medium.
