Abstract

A simple and intuitive formulation is reviewed for the Brewster prism-pair - A most common component in spectroscopy-oriented experiments using ultrashort pulses. This review aims to provide students and beginners in the field of spectroscopy with a unified description of a major experimental component. The total spectral phase experienced by a broadband light field is calculated after passing through a pair of Brewster-cut prisms, demonstrating the flexibility of the prism pair to provide tuned, low-loss control of the dispersion and spectral phase experienced by ultrashort pulses.

Highlights

  • The generation of ultrashort pulses [1,2] revolutionized the field of molecular spectroscopy [3]

  • Many types of pulseshaping techniques and configurations are common in spectroscopyoriented experiments

  • Most applications require only much simpler control of the group delay dispersion (GDD) and higher order dispersion to compensate for the dispersive effect experienced by an ultrashort pulse when passing through optical media and setups

Summary

Introduction

The generation of ultrashort pulses [1,2] revolutionized the field of molecular spectroscopy [3]. Due to the low loss of the prism-pair, it is often the main ’tool of choice’ for intra-cavity applications [17,18,19], low light level spectroscopy [20,21,22], and quantum optics experiments [23,24,25,26,27] This mini-review presents a simple and intuitive formulation of the total wavelength-dependent phase accumulated by light passing through a prism-pair, and demonstrates how this major component is used for tuned, precise control of dispersion and spectral phase
