background: results of various studies suggest that the hypertrophic and keloid scars are highly prevalent in the general population and are irritating both physically and mentally. objective: considering the variety of existing therapies, intense pulsed light (ipl) method along with corticosteroid injection was evaluated in treating these scars. materials and methods: 86 subjects were included...

Intense pulsed light (IPL) systems have evolved since they were introduced into medical practice 20 years ago. Pulsed light is noncoherent, noncollimated, polychromatic light energy emitted at different wavelengths that target specific chromophores. This selective targeting capability makes IPL a versatile therapy with many applications, from the treatment of pigmented or vascular lesions to ha...

BACKGROUND Unlike medical lasers, intense pulsed light (IPL) devices are largely unregulated and unclassified as to degree of safety hazard. With the exception of most of the USA, the United Kingdom and parts of Europe, the Far East and Australia, the sale of IPLs is generally unrestricted, with the majority being sold into the beauty therapy and spa markets. Standards are only imposed on manuf...

BACKGROUND AND OBJECTIVES Laser based therapies are the standard treatment protocol for port wine stain in the United States, but complete removal is infrequently achieved. Intense pulsed light (IPL) offers a broadband light spectrum approach as a viable treatment alternative. Previous studies suggest that IPL can be more effective in treatment of port wine stain by utilizing multiple wavelengt...

Infantile haemangioma therapy has long been a wait-and-see policy. Since recent development of laser and light therapy, pulsed dye laser has been successfully used for treating superficial haemangiomas. Few studies have been published about treatment with intense pulsed light (IPL) to assess the risk/benefit of IPL in the treatment of infantile haemangiomas during their early proliferative phas...

BACKGROUND Pilonidal disease is foreign body reactions accompanied by chronic inflammation that most commonly arises in the hair follicles of the natal cleft or other hair-bearing areas. Today, surgical intervention remains the treatment of choice. But surgical treatment is an invasive method with a high failure rate and recurrence. OBJECTIVES The authors' objective was to assess the efficacy...

There is a clear association between dry eye disease (DED) and skin inflammatory diseases occurring in close proximity to the eyelids, such as facial skin rosacea. Intense pulsed light (IPL) is widely accepted as a treatment for skin rosacea. A number of recent studies demonstrated that, in patients suffering from meibomian gland dysfunction (MGD), IPL therapy also reduces signs and symptoms of...

In solids, high harmonic radiation arises from the subcycle dynamics of electrons and holes under the action of an intense laser field. The strong-field regime opens new opportunities to understand and control carrier dynamics on ultrafast time scales, including the coherent dynamics of quasiparticles such as massless Dirac fermions. Here, we irradiate monolayer and few-layer graphene with inte...

Photofission enables a unique capability for the domain of non-chemical space propulsion. An ultra-intense laser enables the capacity to induce nuclear fission through the development of bremsstrahlung photons. A fundamental architecture and performance analysis of a photofission pulsed space propulsion system through the operation of an ultra-intense laser is presented. A historical perspectiv...
