Bow-Tie Laser Cavity
Application ID: 59771
This type is one of the most popular laser cavities. In particular, it is often used for the Ti-doped sapphire femto-second laser.
The stability of the laser cavity is analyzed by releasing a ray inside the cavity and is traced for a predefined time period that is sufficiently long. Ray tracing continues until the predefined computation time has passed if the laser cavity is stable while the ray gets out of the cavity relatively sooner if not.
A parametric study demonstrates how the spherical mirror position changes the cavity stability and compares the stability result with the ABCD theory. The results show a very good agreement.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
