SESAM parameters

Key design parameters: magnitude and phase of the optical absorption and reflection

SESAM parameters are important for proper laser performance:

saturation fluence: energy level where the device saturates
modulation depth: fully saturated nonlinear reflectivity change
nonsaturable loss: loss of a fully saturated SESAM - should be as small as possible
temporal response: how fast the absorber recovers.

The optical characteristics of the modulation depth, saturation fluence, and non-saturable loss are key for proper laser performance.
