Prism dioptres. Prism correction is commonly specified in prism dioptres, a unit of angular measurement that is loosely related to the dioptre. Prism dioptres are represented by the Greek symbol delta (Δ) in superscript. A prism of power 1 Δ would produce 1 unit of displacement for an object held 100 units from the prism. [2]
CPA for lasers was introduced by Donna Strickland and Gérard Mourou at the University of Rochester in the mid-1980s, [2] work for which they received the Nobel Prize in Physics in 2018. [3] CPA is the current state-of-the-art technique used by most of the highest-power lasers in the world.
Titanium-doped sapphire is the most common tunable solid-state laser, capable of laser operation from 670 nm to 1,100 nm wavelength. Typically these laser systems incorporate a Lyot filter into the laser cavity, which is rotated to tune the laser.
Ophthalmology. Esotropia is a form of strabismus in which one or both eyes turn inward. The condition can be constantly present, or occur intermittently, and can give the affected individual a "cross-eyed" appearance. [1] It is the opposite of exotropia and usually involves more severe axis deviation than esophoria.
A prism compressor is an optical device used to shorten the duration of a positively chirped ultrashort laser pulse by giving different wavelength components a different time delay. It typically consists of two prisms and a mirror.

The PASCAL (PAtterned SCAnning Laser) method of photocoagulation was initially developed at Stanford University. OptiMedica founders worked together at Coherent, and based on their experience in the ophthalmic laser industry, recognized the need for improved safety, precision, comfort and speed of photocoagulation procedures for eye diseases.
"The one thing I love that she's bringing to her sport: More people want to watch. More people want to tune in. ... Don't get it twisted, don't get it f**ked up.
An ultrashort pulse laser is a laser that emits ultrashort pulses of light, generally of the order of femtoseconds to one picosecond.
We might have to wait a little longer to see Benedict Bridgerton fall in love on screen, but in real life, actor Luke Thompson is reportedly dating his co-star Harriet Cains, who plays Philippa ...
