The Institute for Laser Science is department of the University of Electro Communications, located near Tokyo, Japan.
Location
The Institute for Laser Science is located at 1-5-1 Chofugaoka, Chofu, Tokyo, 182-8585, Japan. The coordinates are (+35.657952,+139.54128). The official site is http://www.ils.uec.ac.jp/
Access:
- By train: Keiō Line, Chofu station (about 20 min from Shinjuku by "express"); exit to North, 5 min walk North until road 20, cross road 20, walk left and enter the campus of University of Electro Communications tgrough the Sei-mon (main gate), walk North and West, pass through the "Naka-mon" (central gate) and walk East; the last building at the left hand side.
- By car: Chuo highway, Exit "Chofu", (toward Shinjuku), one block East by road 20, then left (North) at the first traffic signal, then first right through "Nishi-mon" (West gate).
- By walking: from Chofu Airport, walk East until Nogawa river and turn right. FOllow the rivet until road 12, and turn right (south). Continue South pass under the Chuo highway, look left for the "Nishi-mon"(West gate) and enter there. (25 min to walk)
History and achievements
Disk laser (active mirror).
Established in 1980, the Institute specializes mainly in improving the performance of gas lasers, especially excimer lasers. Between 1990 and 2005, the Institute developed fiber disk lasers, disk laser (active mirror)[1] and the concept of power scaling. Ultra-low loss mirror was developed [2] aiming application for high power lasers (1995).
Since 2000, its main research directions have been in the areas of solid state lasers, fiber lasers and ceramics. Since then, the Institute has carried out experiments with quantum reflection of cold excited neon atoms from silicon surfaces. [3] [4]
The institute has also performed the first experiments with quantum reflection [3] of cold atoms from Si surface and, in particular, ridged mirrors [5] for cold atoms and the interpretation as Zeno effect. [6]

In 2004, the Institute developed the first microchip atomic trap. [8][9]
