Designing multilayer optical devices

Using a suitable design strategy, in addition to flexible software, is key for reaching design goals efficiently.

Laser Design: Understanding and optimizing laser resonator designs: An overview

The design of a laser resonator is an essential part of a laser design and often a difficult task—learn how to determine required resonator mode properties and find suitable designs...
FIGURE 1. Optical spectra of the steady-state output pulse of a passively mode-locked fiber laser with an all-normal-dispersion laser resonator have been simulated using RP Fiber Power software; the bandwidth of the intracavity bandpass filter is varied from 3 to 12 nm.

Ultrafast Lasers: Numerical simulation aids design of fiber-based ultrafast laser sources

The design of fiber-based ultrafast laser sources via numerical simulations leads to prototype and product designs with proven handling of nonlinear effects.
