is a three-year collaborative project funded by the European Union
within its 7th Framework Programme.
The project duration has been extended and MIRSURG will be active
until 01 December 2011.
The acronym MIRSURG comes from
Solid-State Laser Systems for Minimally Invasive Surgery.
The MIRSURG project, comprising researchers from
9 European institutes and companies, is focused on development of
a laser source that will enable minimally invasive neurosurgery.
The laser should emit at a wavelength near 6.45 µm and provide
high single pulse energy and average power. The penetration depth
at this wavelength will be comparable to the cell size (several
micrometers), which will make it possible to avoid collateral damage
when ablating the tissue.
Earlier tests carried out in the USA with free electron lasers (FELs)
have proved that brain surgery performed at a wavelength of 6.45
µm leads to good results. Such lasers generate coherent radiation
with very high brilliancy. For applications in biomedicine however,
FELs are not practical since they are coupled to huge and expensive
accelerators. Therefore, it is important to develop new technologies
to replace the FELs with table-top solid-state photonic sources.
The main strategy is to exploit nonlinear optical techniques (OPO)
in combination with novel near-IR laser pump sources (near 1 and
2 µm) and new materials (e.g. orientation patterned GaAs)
to obtain an unprecedented energy level (10 mJ) near 6.45 µm
at a repetition rate of 100 Hz (an average power of 1 W). The systems
will provide improved control and higher accuracy for treatment
and prevention either at individual cell level or cellular structures
depending on the pulse shapes utilized.
The main objective of MIRSURG is to develop advanced
table-top solid-state photonic sources for a specific wavelength
in the mid-IR spectral range, as a practical, reliable and cost
effective alternative to large scale FELs, for an important application
in biomedicine (health): minimally invasive surgery. The project
is coordinated by Valentin Petrov of the Max-Born-Institute
for Nonlinear Optics and Ultrafast Spectroscopy in Berlin, Germany.
