“…The crystal was pumped by a fiber-coupled diode laser with a fiber core diameter of 110 μm and a numerical aperture of 0.22. Diode pumping used ~914 nm wavelength which was previously shown to reduce the effect of thermal lensing [29,30] and increase the laser efficiency [31][32][33][34][35][36].…”

We have demonstrated the highest conical refraction (CR) laser output power to date by placing a CR crystal inside of a diode-pumped Nd:YVO laser cavity. The CR crystal did not have a significant influence on laser output power as well as efficiency. The CR laser produced the maximum output power of 3.68 W with the slope efficiency of 42 % and opticalto-optical efficiency of 34 %. Therefore, this approach could be an attractive pathway for further power scaling of the CR lasers.

“…In such studies, each wavelength can trigger different/simultaneous mechanisms in seed and the induced changes may open new avenues for plant biostimulation. The appropriate source for such experiments can be selected from diode pumped solidstate lasers (Nadimi and Major 2018, Nadimi et al 2017, 2020, Sedaghati et al 2019.…”

With ever increasing world population, the demands on food safety and security are also expected to substantially increase over the next few decades. As agronomic practices, agricultural mechanization and plant breeding technologies have already been extensively exploited, novel techniques need to be explored and implemented to enhance crop production. To this end, the emerging area of laser-based technologies has shown potential to bring about another revolution in enhancing quantity, quality, and safety of foods. This paper presents an exhaustive review of the use of five non-invasive non-destructive laser-based techniques in agriculture, namely laser biostimulation, light detection and ranging, laser land levelling, laser-induced fluorescence spectroscopy, and Raman spectroscopy. Herein we provide the advantages, status quo and challenges of each of these techniques and conclude with recommendations for future work. A comprehensive review of literature reveals the untapped potential of laser applications in agriculture that has the potential to unleash the next agricultural revolution.
