Third 'Rio de la Plata' Workshop on
Noise, Chaos and Complexity in
Lasers and Nonlinear Optics


Punta del Este, Uruguay, 3-7 December, 2007



Scientific Organizers: C. Masoller (Uruguay) A. Hnilo (Argentina)

The topics covered by the workshop include: dynamics of lasers and optical amplifiers, noise properties, instabilities and multimode behaviour, quantum-dot and novel types of semiconductor lasers, laser arrays, light-polarization dynamics, transverse spatial patterns, solitons and localized structures, synchronization and applications to secure communications, photonic crystals.

The purpose of the Workshop is to keep the scientific community working on nonlinear phenomena on lasers and optics, updated with the most recent developments and tendencies in the area. We hope that the Workshop will provide the opportunity to interchange ideas in a relaxed environment, contributing in this form to the possible nucleation of new inter-institutional collaborating groups and encouraging the development of scientific collaborations at an international level. Emphasis will be put in the participation of Latin-America scientists.

Punta del Este is located 140km (87 miles) east of Montevideo is a charming and busy coastal resort that  was founded at the beginning of the 19th century. Opposite the peninsula that separates the waters of the Atlantic Ocean and the Rio de la Plata, is the island of "Isla de Lobos", inhabited by one of the world's largest sea-lion  colonies.

The Workshop will take place at the Club del Lago Hotel*****, that  is located 20 minutes from Punta del Este center and just 3 kms. from the Carlos Curbelo International Airport. Highlights of the Hotel include the adjacent 18-hole golf course and its particularly peaceful location, with magnificent views of  the Lagoon.

To make your hotel reservation, please contact the hotel directly, by telephone, email or fax, indicating  your arrival and departure days, accompanying person if any, and mention "Laser Workshop participant".  Contact information:
Tel: (59842) 578403

Special rates
for the Workshop,  per person per night in single or double room occupancy, in the "All Inclusive Plan"  (Buffet breakfast, lunch, and dinner)

participant:  US$ 63 , accompaning person: US$ 83 (in US dollars).


Arrival information:


By Plane: in December several companies fly directly from Buenos Aires (Argentina) and San Pablo (Brasil) to Punta del Este.  The International Airport Carlos Curbelo is 3 kms. from the hotel. If you inform in advance the hotel of your arrival plans (, the hotel can arrange a transfer free of charge. Alternatively, you  can take a taxi or remise from the airport to the hotel (the cost is about US dollars10-20).

By bus: From Montevideo Carrasco Airport there are frequent buses to Punta del Este (COT and COPSA). The trip to Punta del Este takes less than 2 hours.  You must leave the bus at "Solanas Terminal" (before Punta del Este). From the but terminal you can call the hotel (tel: 578403) and they will arrange a tranfer free of charge, or, alternatively, you can take a taxi from the bus terminal "Solanas" to the hotel (the cost is about US dollars10).

Registration Fee:

Has to be paid cash at the conference registration desk (prices in US dollars). It includes the welcome cocktail, coffee breaks and the book of abstracts
