This thesis is an exploration of numerical modeling and design of intra-cavity
frequency doubled green lasers, which is one of the three key light sources in laser
display systems. In this thesis the time-domain traveling wave (TDTW) model, which is well
developed to model integrated photonic devices, is derived for modeling and
design of a new proposed device. The device is based on the intra-cavity
frequency doubling of high power distributed Bragg reflector laser diodes (DBRLD)
and MgO-doped periodically poled lithium niobate (MgO:PPLN)
waveguides. The numerical modeling and design suggest the superiority of the
proposed intra-cavity frequency doubled DBR-LD/MgO:PPLN green laser over
traditional single-pass frequency doubled DBRLD-LD/MgO:PPLN green laser. A plane-wave based coupled-wave model is implemented to model miniature
intra-cavity frequency doubled DPSS lasers. Good agreement between the planewave
model and experiment has been obtained. By employing the plane-wave
model, we have explained the phase problem in our optical contact
Nd:YVO4/MgO:PPLN green laser. Design examples of wide temperature
operation of Nd:YVO4/MgO:PPLN green lasers are also completed by this
numerical method. Finally, to model high power bulk intra-cavity frequency doubled diodepumped solid-state (DPSS) green lasers, a three-dimensional coupled-wave model
is developed and compared with experimental results. A two-dimensional thermal
model is incorporated into the three-dimensional coupled-wave equations to
model thermal lensing and thermal de-phasing effects in intra-cavity frequency
doubled DPSS lasers. The numerical models we developed are validated by the
experimental results. / Thesis / Doctor of Philosophy (PhD)
