Mathematical modeling is used to estimate the performances of the three-micron Er:YAG laser in various generation regimes. The model, based on simple rate equations, uses exclusively spectroscopic ...

Laser and surgical treatment is typically combined with medical treatment. Primary angle closure suspect (PACS): Comment: Not all patients with PACS need laser peripheral iridotomy (LPI). Evidence ...

Background Corneal nerve damage after laser epithelial keratomileusis (LASEK) is thought to be the cause of dry eye and pain. Therefore, we investigated whether taking pregabalin (Lyrica), which ...

A high peak power (>MW), passively Q-switched Yb:YAG/Cr:YAG micro-laser end-pumped by fiber-coupled 120-W QCW LDs (Repetition rate <; 100 Hz) is developed. The convex output coupler with a curvature ...

In the 1980s, translucent YAG ceramics were developed 35, 36, 37, but poor laser oscillation was obtained because it was difficult to achieve high-optical-grade properties with these materials.

A new Superman trailer has revealed lots of new footage, giving fans a good idea of what to expect from the DC Universe blockbuster when it comes out in July.
