Abstract
A theoretical analysis of oscillation characteristics is developed for Ti-diffused Nd:MgO:LiNbO3 waveguide lasers by using the formalism of mode overlap. Simple and explicit expressions in terms of mode sizes are derived for effective mode volume and coupling efficiency between pump mode and laser mode, which are directly proportional to the threshold pump power and slope efficiency, respectively, both for transverse and coaxial pumping considering the spatial distribution of the pump beam and the laser beam. A comparison for the two pumping configuration has shown that the transverse pumping requires much higher input pump power and has much lower slope efficiency than the coaxial pumping. The fundamental transverse mode (TM 0) oscillation conditions relative to the cavity loss are also discussed for the two pumping configurations. Indexing terms: Ti-diffused Nd:MgO:LiNbO 3 waveguide laser, effective mode volume and coupling efficiency, threshold pump power and slope efficiency, transverse and coaxial pumping, single mode oscillation condition.
