• Apr 24, 2026 lasers in dentistry guide for clinical practice e expertise Endodontics Lasers are employed for: Disinfection of root canals Removal of intracanal biofilm Access cavity preparation Features: Nd:YAG and diode lasers are most common in endodontic applications. Effective in reducing bacteria, especially in complex root canal systems. Pr By Arvilla Tremblay
• Nov 20, 2025 engineering physics i lasers laser action tical gain, which must overcome losses due to scattering, absorption, and mirror imperfections to sustain laser oscillation. Laser Threshold Condition The minimum gain needed for laser oscillation is called the threshold gain. It depends on the cavity length, mirror reflectiviti By Mr. Anahi Shanahan Jr.
• Jul 21, 2026 crystalline lasers physical processes and operatin se ions have discrete energy states within the crystal lattice, and laser action involves transitions between specific energy levels. Ground State: The lowest energy level of the dopant ion. Excited States: Higher energy levels accessible via energy absorption. Metastable States: Excited states wi By Sedrick Franey
