  • Lasers in Action: Revolutionizing Science, Industry, and Beyond
    Umakant Shrivastava, Abhay Gupta
    Laser Materials Processing and Manufacturing Techniques, 2026
    Lasers are increasingly being used in an astonishing variety of scientific, engineering, medical, and commercial applications. This review surveys briefly some of these applications: basic research, materials processing, analytical and diagnostic applications, information transmission and storage, measurement and alignment, and photochemical and biomedical applications. The ruby laser, developed in 1960, marked the beginning of laser technology. Over the past 30 years, lasers have evolved significantly, offering a wide range of wavelengths in the visible and near-visible spectrum, with options for continuous or precisely controlled pulsed operation. This versatility has expanded their applications in science, engineering, and medicine. Beyond traditional gas, solid- state, and semiconductor lasers, newer types such as tunable free-electron lasers, optical parametric oscillators, and coherent anti-Stokes Raman photon generators enable access to previously unavailable wavelengths. Up-conversion mirrors can shift these wavelengths into the blue spectrum, addressing gaps in traditional light sources. Blue and green lasers are particularly useful for data storage, transmission, and display technologies. In medicine, neodymium-YAG and holmium-YAG lasers have revolutionized laparoscopic therapies, especially for kidney stone removal since 1986. Nearly half of the 59,000 annual kidney stone surgeries now use laser-based techniques, such as dye laser rubber band ligation. Additionally, diode lasers provide an alternative by using hemoglobin's thermal absorption to seal veins, demonstrating further medical advancements. Laser technology continues to grow, with combustion diagnostics in engines and power plants also benefiting from these innovations.
  • The Evolution of Laser and Laser Technology in Industrial Applications
    Umakant Shrivastava, Saurabh Mitra
    Laser Materials Processing and Manufacturing Techniques, 2026
    Lasers moved rapidly from the Nobel Prize-winning principle of stimulated emission in 1956 to the demonstration of optically pumped microwave amplification in 1958 and the first laser devices, in the visible part of the spectrum, in 1960. The fiber laser was first proposed in 1961, and the continuous wave (CW) carbon dioxide laser followed in 1964. In the same decade, significant advances in the power and efficiency of the yttrium-aluminium garnet (YAG) laser set the stage for their adoption in production environments during the 1970s. Recent advancements in high-power CW fiber lasers have renewed interest in their applications. A numerical simulation system for laser cutting of hydro-formed zinc-coated dual-phase steels has been developed using adapted 3D finite element welding and machining codes. The model incorporates a defined laser-material coupled zone (DLCZ) and moving heat flux to simulate thermal and mechanical effects. Experimental results align well with simulations at a coupled frequency of 1 × 10 8 W, though residual zinc coating near cut edges remains an issue. Improved cut speeds and spatter reduction are observed at 8×10 8 W. Additionally, Nd:YAG lasers have seen progress in 2010, with studies on optical arrangements for better weld geometry in stainless steel. Advances in workpiece-nodal-mesh schemes have enhanced knowledge in laser welding. However, few studies quantify the impact of test-piece arrangement on heat distribution or explore the relationship between laser beam profiles and weld outcomes, despite their significant influence.
  • A study on components of fly ash of different locations and its utilization for production of improved quality materials: A Review
    Umakant Shrivastava, Mohammad Ziyauddin Khan, Vikas Mishra
    Iop Conference Series Materials Science and Engineering, 2020
    During the combustion of coal for energy production an industrial by-product is generated known as Fly Ash, is recognized as a hazardous environmental pollutant. Globally, a lot of considerable research has been undertaken by the researchers and scientists on this subject because of various environmental problems caused by Fly Ash. In recent past it is only being treated as waste and a source of air and water pollution but is in fact a resource material and has also proven its worth over a period of time. The present paper reviews on the potential applications for coal Fly Ash as a eco-friendly raw material: in construction of building materials like bricks and Portland cement, in painting application, application in TL Dosimetries, as a soil amelioration agent in agriculture, in the synthesis of zeolite, in the synthesis of geo-polymers, as an adsorbent for flue gases, as a removal agent for toxic metals, dyes, organic & inorganic compounds from waste water and for the extraction of the metals. Since at different locations the property of Fly Ash varies; thus we required analyzing its variability parameter for utilizing it effectively. Hence, before the utilization of Fly Ash as a eco-friendly resource material, it is necessary to study properties of Fly Ash from different sources, so that it can be used beneficially. Thus Fly Ash management is a cause of concern for the future. This article attempts to highlight the management of waste Fly Ash to make use of this solid waste, in order to save our environment.
  • Thermal insulation ceramic material by using coal combustion waste fly ash and waste glass with medicinal phytochemical repellent
    Saroja Kumar Sahoo, Umakant Shrivastava, Mohammad Ziyauddin Khan
    Iop Conference Series Materials Science and Engineering, 2020
    Toreduce in environmental load from pollution after primary using of various products (waste product), which is supporting to secondary utilization in preparation of thermal insulation materials using coal fly ash (40-60%), siliceous glass material(30-55%), some phytochemical medicinal additives and (2-8%) cellulose. We know that thermal energy is effective for nature. By the scientific ideas and methods ‘energy’ has been presenting a greatest continuous chainthat frequently more economical to transforms the various form of ceramic materials. The capability of ceramic material such as “tiles”, cooking utensil, crucible etc chosen the better quality for treatment of heat insulation materials based on waste coal combustion of fly ash with waste glass and regular active form of adding medicinal organic adsorbates. In heretheorganic medicinal additives acts as reducing over materials from harmful diseases of microbial. It is favor for developing to high response to health care purposing. Over the materials, thermal activitydepends on some factors such as chemical composition of substances. From this typical point, the Fly Ash and Waste Glass reduce the flow of heat. To testing after preparation of materials as water absorption in boiling and cold water acts with (4-5) days. By the thermal treatment, the material individually acts as (700-1000)˚C. The mechanical durability with other physical and chemical properties for this material is supporting with environmental parameters.
