Calculation and experimental verification of a collimator with a Kerr lens for fibre laser mode locking

We present the calculation and experimental verification of the operation of a collimator coupling a light beam into an optical fibre with an As2S3 nonlinear plate. It is shown that a Kerr lens formed in the plate with an increase in the peak pulse power leads to an increase in the output coupling r...

Summary:We present the calculation and experimental verification of the operation of a collimator coupling a light beam into an optical fibre with an As2S3 nonlinear plate. It is shown that a Kerr lens formed in the plate with an increase in the peak pulse power leads to an increase in the output coupling ratio by about 15%, which can be used for the passive mode locking of a fibre laser.
