Inductively Coupled Plasma Atomic Emission Spectroscopy: Principle

Inductively coupled plasma (ICP) is the most widely used plasma source in atomic emission spectroscopy (AES), also known as Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). The ICP source, or torch, consists of three concentric quartz tubes with argon gas flowing through them. A spark from a Tesla coil initiates the ionization of argon, generating a high-temperature plasma.
The ions and electrons produced interact with the fluctuating magnetic field created by a water-cooled...

  • Optical Parametric Chirped-Pulse Amplification (OPCPA) offers a promising route to generate such pulses.

Purpose of the Study:

  • To develop a short-pulse seed source utilizing OPCPA technology.
  • To characterize the generated pulses for suitability in high-energy systems.
  • To explore the potential for generating even shorter pulses and broader bandwidths.

Main Methods:

  • Implementation of an OPCPA-based short-pulse laser source.
  • Characterization of the output pulse properties, including wavelength, bandwidth, and duration.
