“…The radiation dose effects on fibre-optic LIBS using a ceramic micro-laser was assessed by Tamura et al , focusing on the impact of 0–10 kGy h −1 dose rates on laser operation properties when measuring Zr metal. 168 Whilst the signal reduced with increased dose (mainly due to pulse energy reduction), useful spectra were obtained at the maximum dose rate, suggesting the system is applicable to remote elemental analysis in harsh environments.…”

“…272,273 FO-LIBS for nuclear research has also been employed by several research groups with systems ranging up to 100 m in length. 271,272,[274][275][276][277] Other elements that are commonly measured in-core as indicators of potential structural failures or material damage include Cr, Mn, Mo, Ni, Si, and V, where limits of detection range from around 100 to 200 parts per million (ppm). 271,274,[277][278][279] Crucial research efforts also include developing instrumentation to provide more affordable alternatives to Nd:YAG lasers that are typically implemented with the current detection systems.…”

“…271,274,[277][278][279] Crucial research efforts also include developing instrumentation to provide more affordable alternatives to Nd:YAG lasers that are typically implemented with the current detection systems. For example, Tamura et al 275,276 developed a microchip laser FO-LIBS system that could potentially offer a cheaper alternative to the typical Nd:YAG lasers used. This system was tested using radiation doses up to 10 kGy/h, where adequate signals were obtained under these conditions.…”

The development of measurement methodologies to detect and monitor nuclear-relevant materials remains a consistent and significant interest across the nuclear energy, nonproliferation, safeguards, and forensics communities. Optical spectroscopy of laser-produced plasmas is becoming an increasingly popular diagnostic technique to measure radiological and nuclear materials in the field without sample preparation, where current capabilities encompass the standoff, isotopically resolved and phase-identifiable (e.g., UO and UO[Formula: see text]) detection of elements across the periodic table. These methods rely on the process of laser ablation (LA), where a high-powered pulsed laser is used to excite a sample (solid, liquid, or gas) into a luminous microplasma that rapidly undergoes de-excitation through the emission of electromagnetic radiation, which serves as a spectroscopic fingerprint for that sample. This review focuses on LA plasmas and spectroscopy for nuclear applications, covering topics from the wide-area environmental sampling and atmospheric sensing of radionuclides to recent implementations of multivariate machine learning methods that work to enable the real-time analysis of spectrochemical measurements with an emphasis on fundamental research and development activities over the past two decades. Background on the physical breakdown mechanisms and interactions of matter with nanosecond and ultrafast laser pulses that lead to the generation of laser-produced microplasmas is provided, followed by a description of the transient spatiotemporal plasma conditions that control the behavior of spectroscopic signatures recorded by analytical methods in atomic and molecular spectroscopy. High-temperature chemical and thermodynamic processes governing reactive LA plasmas are also examined alongside investigations into the condensation pathways of the plasma, which are believed to serve as chemical surrogates for fallout particles formed in nuclear fireballs. Laser-supported absorption waves and laser-induced shockwaves that accompany LA plasmas are also discussed, which could provide insights into atmospheric ionization phenomena from strong shocks following nuclear detonations. Furthermore, the standoff detection of trace radioactive aerosols and fission gases is reviewed in the context of monitoring atmospheric radiation plumes and off-gas streams of molten salt reactors. Finally, concluding remarks will present future outlooks on the role of LA plasma spectroscopy in the nuclear community.

“…11 Continued advances have led to the development of micro-LIBS, which uses composite ceramic micro-lasers pumped by a quasi-continuous (CW) diode laser. [12][13][14][15] The micro-LIBS has several advantages over standard LIBS, including a lightweight head sensor that can be easily attached to a robotic arm and an inexpensive, single-use ceramic probe essential for core nuclear detection applications. Verication experiments for uranium determination showed high accuracy when uranium was determined at 800 Gy h −1 .…”
