About us

The Applied Terahertz Science Group is one of the pioneers in terahertz spectroscopy in Mexico.

We aim to innovate in the development of time-domain spectroscopy and its applications. Our projects involve collaborations with specialists in many areas, such as Physics, Biology, Biochemistry, Medicine, Art Conservation, Industry, etc.

We started as part of Bernardo Mendoza's group at Cantro de Investigaciones en Optica A.C. in 2009 with whom we maintain a collaboration. In 2013 we became an independent research group and established the Terahertz Laboratory (TERALab) wich is currently one of the top facilities in the country in this discipline. The group has produced 6 master graduates and 3 undergraduate thesis and currently there are 6 other students working on their PhD, Masters or undergraduate projects.

All of our Masters and PhD students are fully funded by Consejo Nacional de Ciencia y Tecnologia (CONACyT). We have obtained support from Centro de Investigaciones en Optica (CIO) in order to refurbish the space that now houses our Terahertz Laboratory (TERALab). In addition several grants from CONACyT have allowed us to equip it. We built an amplifier based Optical-Pump Terahertz-Probe Time Domain spectrometer and also have a fiber coupled time domain spectrometer and imaging system. We also have access to numerous "common use" facilities that include an electron microsocopy laboratory, optical, thin film, and mechanical workshops among others.

We are part of Centro de Investigaciones en Optica A.C. We are based in the city of Leon in th state of Guanajuato in Mexico. Leon is a modenr industrial city traditionally dedicated to the fabrication of leather and footware. The car manufacture industry has also grown dramatically in the region over the last few years. Leon is about 1.7 million inhabitants, despite of its size, remains a relatively peaceful city with a growing cultural and academic offer.


1 January 2009
Enrique Castro Camus was appointed Research Professor at CIO in order to establish a research group in the topic of Terahertz Spectroscopy.

14 November 2009
The Laboratorio de Optica Ultrarrapida (LOU) was constucted as a facility for CIO. Ramon Carriles became technical responsible and Enrique Castro technical co-responsible of the lab.

23 February 2010
A 3.5mJ regenerative amplifier was installed and the LOU started opperating.

20 December 2010
Our first grant was awarded.

29 August 2011
Our first THz pulse was recorded! (perhaps the first one in Mexico?)

1 December 2013
The Applied Terahertz Science Group was formally created.

28 March 2014
Our second TDS system became operational!
