I'm an experimentally oriented physics student and have been fascinated by lasers for a longer time. I'm currently building a diode-pumped, frequency-doubled Nd:YVO4 laser from scratch. Before I start fiddling with the delicate optics and possibly shoot up some expensive parts, I'd like to model the laser cavity on a sheet to find out the optimal parameters.
The only good resource I found is optique-ingenieur.org which covers basic topics like the rate-equation and threshold conditions as well as the ABCD matrix formalism.
This is the direction I need further information in, especially the following points:
- how I can extend the ABCD matrix method when both the fundamental and the second harmonic are circulating in the cavity ?
- optimal cavity length
- beam waist and divergence
- resonator stability, sensitivity to misalignments
- slope efficiency (pump power vs. anticipated output power)
- in future: thermal effects (Thermal lensing, crystal fracture)
Where possible, I want to model it by hand and don't use simulation software.
The cavity will be of linear type:
|PUMP+OPTICS|--|HR@w| Nd:YVO4 |HR@2w|---|LBO for SHG|---|OC (HR@w,HT@2w)|
I would be very happy if anyone knew some useful books or resources towards these questions.
