A system and a method of designing and mechanical packaging of pumped laser resonator elements to minimize their size. All the elements of the compact pumped laser resonator assembly (5) are placed on a monolithic block mount (10), which substitutes for and functions as a laser diode heatsink a laser , resonator cavity mount, and an optical bench. The laser optical cavity is in the form of a laser path (11) defined within the monolithic block mount (10) and includes a plurality of bends (40) in order to decrease the size of the assembly. The laser resonator optical elements include fold prisms (22 24), a , reflector (38), a retroreflector (32) and an intracavity optical Q-switch (30). …

Why it's free to use
- Filed June 8, 1998 and granted April 30, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 8, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 8, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
