When discussing lasers, coherence represents the ability of a wave function — which describes the action of photon particles — to interfere with other wave functions. (In this case, this type of ...

Any advance in laser tech has huge potential across a whole range of fields – from space comms to fusion power – and we just got a big one: ultra-short laser pulses of up to 100 megawatts, the most ...

Can light itself, perhaps from a laser, cast a shadow? It might seem like a trick question, but the answer to this is "yes." ...

Their approach is inspired by the way bacteria and other plants and organisms convert light energy into chemical energy - a ...

A new test that uses lasers to detect different types of dementia in just seconds could “revolutionise” how the disease is diagnosed, scientists have said. Researchers at the University ...

Expect minimal downtime (1-2 days of swelling, 2-4 days of redness, 4-7 days of peeling). Candela V-Beam Laser (Pulsed Dye Laser). A good option for erythematous, hypertrophic or keloidal scars. The ...

The depletion layer — the region between p- and n-type materials — takes on interesting electrical properties which make it useful in many different semiconductor applications. In the case of diode ...
