An Ultrastructural Study of Corneal Incisions Induced by an Excimer Laser at 193 nm

Laser Thermal Ablation

“…The 0.5-1.0 pm penetration depth at 193 nm produces a sharp and extraordinarily fine cut with less than 1 pm of thermal damage (Marshall et al, 1985). At this wavelength there is sufficient photon energy (6.2 eV) that molecular bond breaking is expected and ablation is not totally due to thermal processes.…”

UV light generation in optical fibres

“…Coherent UV light generation has numerous potential applications including lithography, biomedical and explosives detection [1][2][3]. To date, two main approaches were adopted: 1) the use of nonlinear crystals for harmonic generation of a near IR laser, or 2) excimer gas lasers.…”

The 2014 Bowman Lecture—Bowman’s and Bruch’s: a tale of two membranes during the laser revolution

“…40 There followed several years of active collaboration between us and many publications, which highlighted the potential of a laser system emitting at 193 nm for refractive surgery. [41][42][43] In Excimer lasers, atoms of inert gases are forced to combine transitorily with halogen atoms under high pressure and huge electrical voltages. The combination of argon and fluorine atoms under such circumstances results in a high-energy particle, which is unstable and wants to revert to its component parts as quickly as possible.…”
