Lumenis UltraPulse – High-Peak-Power CO₂ Laser for Fractional and Surgical Resurfacing

Описание: This video presents a technical overview of the Lumenis UltraPulse system, a high-peak-power CO₂ laser platform used for fractional and full-field ablation in dermatologic and surgical applications. The presentation reviews the main subsystems, including the CO₂ laser source, articulated arm or fiber delivery, scanner handpieces, spot-size and pattern controls, footswitch interface, and cooling and safety interlocks. The video explains how very short, high-energy pulses generate controlled ablation and coagulation zones in soft tissue, and how fractional scanning creates microthermal zones to treat a portion of the surface while leaving intervening skin intact.

Key topics include pulse modes and parameters (energy, pulse duration, repetition rate), spot size and fluence selection, fractional density and pattern geometry, and differences between fractional resurfacing and full-field ablation from an energy-delivery standpoint. The workflow for system setup, calibration checks, and basic beam alignment is summarized at a conceptual level, together with engineering considerations such as plume evacuation, eye safety, and integration with smoke evacuation systems. The content is intended for students, clinicians, and biomedical engineers interested in medical lasers, dermatologic and ENT laser systems, and optical device design, and is provided solely for educational and informational purposes without clinical or treatment recommendations.
