"Огледало на държавника е отговорността му пред бъдещето"
In website of News.bg (in Bulgarian)
Продължение на разговора с доц. Иван Бъчваров – за емигрирането на български учени, за науката като движеща сила на обществото, за избора между усвояването и съзиданието. За мисията на държавника. За бъдещето...

"Учим студентите да предизвикват късмета"
In website of News.bg (in Bulgarian)
Едно интервю с доц. Иван Бъчваров по повод Деня на народните будители. Днес немалка част от младите учени напускат България, следвайки своят път на реализация. Много от тях вече имат утвърдено международно признание за своите професионални достижения. Но ще бъде грешка да мислим за тях като за изгубено съкровище. Отивайки в различни точки на света, те съхраняват връзката си с родината и с университета, от който са тръгнали. Готови са да споделят опита и откритията си, да помагат за развитието на България. Но какво правим, за да интегрираме страната си към света, чийто облик се определя от развитието на науката, образованието и високотехнологичната индустрия?

April 2014. At the Physics department of Sofia University, we held the new lab opening ceremony.
By a special invitation, the opening ceremony was honored by the president of the Republic of Bulgaria Rosen Plevneliev and attending officials: Anna-Marie Vilamovska - Secretary for Healthcare, Education and Science of the President of the Republic of Bulgaria, M-r Martin Ivanov - Secretary for Culture, Education and National Identity of the President of the Republic of Bulgaria, and M-r Evgeny Angelov - Economic Advisor to the President of the Republic of Bulgaria.
Special guests of the event were the rector of Sofia University Prof. Ivan Ilchev, M-r Ivaylo Penchev, CEO and founder of Walltopia Ltd, as well as many other leaders from Bulgarian academia and business.

Thankfully to the generous donations by the sponsors from three leading Bulgarian companies - Walltopia LTD (Ivaylo Penchev), Extrapak LTD (Veselin Georgiev) and Synthesia LTD (Nedko Hristov), we were able to make a complete renovation and transformation of the rooms from an empty storage place to a modern scientific laboratory. The new facility will provide additional 150 square meters of laboratory space, ready for new developments in the field of lasers and their applications.
Prof. Buchvarov introduces the guests to the current projects and advancements in our Laboratory of infrared laser sources and nonlinear devices.
A quick group shot with the President. After wishing us a good luck, Mr. Plevneliev was off to Brussels, and we were set with new enthusiasm for scientific breakthroughs.
On behalf of the whole group I would like to express my deepest gratitude to all the donators without whom this opening ceremony would not take place.

February 2012. Dr. Ivan Buchvarov receives award for the best research activity for year 2011 from the Physics Department of the University of Sofia "St. Kliment Ohridski".
After a highly competitive three stage selection procedure, on 12. 12. 2011 leading Bulgarian investment company Karoll Inc. awarded first place to Ph.D. student Hristo Iliev in its annual competition for graduate students. Mr. Iliev is part of the research group for solid state lasers and nonlinear optics at the Department of Physics (Sofia university) headed by assoc. prof. Ivan Buchvarov. The jury assessed the subject of his dissertation - "Generation of short laser pulses in the near infrared region with wavelengths between 1 and 2 micrometers" as significant for the future development of laser technology as a whole. Mr. Iliev�s doctoral research is a part of a larger project coordinated by Prof. Ivan Buchvarov, which aims to create a new tunable source of laser radiation in the spectral region around 3 micrometers. The main results of previous research of the doctoral student has been published in journals with the highest impact factor in the field of optics and laser technology - Optics Letters and Optics Express. Karoll Inc. provides a ten months scholarship to Mr. Hristo Iliev.
