SC352 - Introduction to Ultrafast Pulse Shaping--Principles and Applications

Tuesday, 15 May
12:00 - 15:00

Short Course Level: Advanced Beginner (basic understanding of topic is necessary to follow course material)

Instructor: Marcos Dantus, Michigan State Univ., USA

Short Course Description:

Pulse shaping is an integral part of every femtosecond laser, and learning about pulse shaping can help us better understand dispersion, pulse characterization and pulse compression. This course begins by describing how the spectral phase affects the temporal characteristics of a femtosecond pulse with a hands-on computer simulation. The essential physics and a brief background of the development of shapers are provided. The course goes over the experimental implementation requirements and then covers some of the most salient applications of pulse shapers, among them: (a) pulse compression, (b) pulse characterization, (c) creation of two or more pulse replicas, and (d) control of nonlinear optical processes such as selective two-photon excitation and selective vibrational mode excitation (e) material processing, (f) microscopy and others. The course provides a good foundation for those wanting to explore the more fundamental aspects of light-matter interactions, and it also provides multiple examples of practical applications that are made possible by pulse shaping.

Short Course Benefits:

This course should enable participants to:

  • Gain a better understanding of femtosecond laser pulses and their applications

  • Learn pulse shaper design principles

  • Compare among different pulse shaper designs and to determine which one is best suited for a particular application

  • Simulate the output pulse from a pulse shaper given a particular phase and amplitude modulation

  • Predict the effect caused by introducing a simple phase such as a linear, quadratic or cubic function on a transform-limited pulse

  • Learn two different approaches to creating pulse replica that can be independently controlled with attosecond precision in the time domain using the pulse shaper

  • Measure the spectral phase of laser pulses using the pulse shaper itself as the measurement tool, and eliminating phase distortions to compress the output pulses

  • Summarize the advantages of having an adaptive pulse shaper for controlling the output of ultrafast lasers

Short Course Audience:

This course, updated yearly, is intended for everyone that uses or intends to use femtosecond laser pulses in academic research or industry. Attendees will learn how pulse shaping can greatly enhance femtosecond laser applications.  No prior knowledge about pulse shaping is required.
