“…Thus, predictions for a Gaussian beam profile are valid for this study. Under a Gaussian spatial beam profile, the laser ablation diameter D is relative to the energy fluence, which can be expressed as shown in the following equation [23,24]: Schematic of an ultrafast laser system with a femtosecond laser source used to micromachining CIGS-based PV modules.…”

“…PBM's positive or negative effects are partially correlated with the generation of mitochondrial ROS [144]. As previously reported, PBM at low dosages induces low amounts of mitochondrial ROS that are crucial in modulating cellular signaling pathways [145, 146]. PBM can activate cellular apoptotic pathways and cause excessive levels of ROS when administered at larger dosages (for instance, 120 J/cm 2 ) [147].…”

Photobiomodulation (PBM) therapy is an innovative treatment for neurological and psychological conditions. Complex IV of the mitochondrial respiratory chain can be stimulated by red light, which increases ATP synthesis. Additionally, the ion channels' light absorption causes the release of Ca2+, which activates transcription factors and changes gene expression. Neuronal metabolism is improved by brain PBM therapy, which also promotes synaptogenesis and neurogenesis as well as anti‐inflammatory. Its depression‐treating potential is attracting attention for other conditions, including Parkinson's disease and dementia. Giving enough dosage for optimum stimulation using the transcranial PBM technique is challenging because of the rapidly increasing attenuation of light transmission in tissue. Different strategies like intranasal and intracranial light delivery systems have been proposed to overcome this restriction. The most recent preclinical and clinical data on the effectiveness of brain PBM therapy are studied in this review article.This article is protected by copyright. All rights reserved.

“…Furthermore, LLLT, induces the synthesis of transcription factors. This phenomenon is regulated by increasing ROS production, which causes increased production of hydroperoxide anion and finally increased concentration of H 2 O 2 [14][15][16]. In turn, the above changes influence transcription factors the most important of the nuclear factor kB (NF-kB) and Activator protein 1 (AP-1) ( Figure 2).…”

Lasers nowadays have several applications in many research fields. In the life sciences and especially in Periodontology, Low Level Laser Therapy (LLLT) has proven to be particularly interesting. Low intensity radiation in specific wavelengths has been known to trigger cellular proliferation and differentiation, through molecular mechanisms that are still not fully elucidated. These effects might be triggered by mitochondria and through Reactive Oxygen Species (ROS). These in turn, can activate other molecular pathways and signaling cascade, resulting in the activation of a plethora of transcriptional factors. In this review we aim to highlight the mechanism of action and the effects of LLLT. We also aim to highlight how different wavelengths and energy applied can have a distinct impact on the effectiveness of LLLT. Finally, we provide insight on its current and potential future applications.
