A pulsed 0.3 T magnetic field was used to heat and compress a low-temperature laser produced copper plasma. The magnetic field was generated using a planar 3-turn coil positioned 10 mm above the ablation spot. The plasma flowing through a central aperture in the coil was strongly focused. Inductive heating of the plasma caused a large enhancement of the overall visible light emission and the appearance of Cu II line emission. The plasma focusing is also evident in the constriction of the spatial distribution of deposited copper. The plasma heating and focusing can be explained in the framework of resistive magnetohydrodynamics.

Laser‐induced breakdown spectroscopy (LIBS) is a laser‐based technique that can provide nonintrusive, qualitative and quantitative measurement of metals in various test environments. LIBS is an emission‐type technology that has been successfully applied to gas, liquid, and solid samples. The major advantages of LIBS compared to other analytical techniques is that no time‐consuming sample preparation is necessary. LIBS uses the plasma generated by a high‐energy laser beam to prepare and excite the sample in one step. It has the ability to perform multielement real‐time analysis. Its major disadvantage is that the excitation condition is sensitive to the fluctuation of environmental conditions as well as the laser energy, which can result in poor measurement precision. The small amount of sample material used in LIBS analysis also gives poorer sensitivity for some metals compared to inductively coupled plasma atomic emission spectrometry (ICPAES) and atomic absorption spectrometry (AAS). The potential of LIBS to detect toxic metals in harsh environments was recognized in the early 1970s. Recent developments towards improving its analytical capability has led to more applications. This article reviews the analytical applications of LIBS with an emphasis on environmental monitoring. A brief review of some fundamental LIBS studies is also given. The analytical abilities of LIBS are compared with some spectroscopic techniques commonly used in the laboratory, such as AAS, ICPAES, and X‐ray fluorescence spectroscopy (XFS).

Laser‐induced breakdown spectroscopy (LIBS) is a laser‐based technique that can provide nonintrusive, qualitative, and quantitative measurements of elements in gas, liquid, and solid samples. Two major advantages of LIBS, a method of atomic emission spectroscopy (AES), compared with other emission techniques, are that time‐consuming sample preparation is not necessary and measurements can be done rapidly. LIBS uses the plasma generated by a powerful laser pulse to prepare and excite the sample in one step. It also has the ability to perform simultaneous multielement analysis. A major disadvantage is that the sample excitation conditions are sensitive to variations in laser parameters and characteristics of the sample, thereby limiting analytical performance. The small amount of sample material used in LIBS analysis also limits detection sensitivity for some elements compared with inductively coupled plasma atomic emission spectrometry (ICPAES) and atomic absorption spectrometry (AAS). The potential of LIBS to detect toxic metals in harsh environments was recognized in the early 1970s. Recent developments toward improving its analytical capability have led to additional applications. This article reviews some applications of LIBS with an emphasis on environmental monitoring. A brief review of some fundamentally directed LIBS studies is also presented. The analytical abilities of LIBS are compared with other spectroscopic techniques commonly used in the laboratory, such as AAS, ICPAES, and X‐ray fluorescence spectroscopy (XRF).
