Blue laser

Development of a new family of high-power blue fiber lasers

About the project :


The 488-nm blue wavelength corresponds to a clearly identified need in the field of high power lasers, for applications interesting to the bio-medical instrumentation field. The most significant relevant markets are DNA sequencing, flow cytometry and laser Doppler anemometry.


Laser equipment capable of meeting the needs for the upgrade and the development of related equipment parks are based on diode-pumped, micro-structured fiber optic technology, with frequency conversion of the infrared flux produced by the source. The frequency conversion takes place in a ferroelectric crystal with periodic domain inversion (PPLN), capable to provide excellent power yield. The high  power levels achieved and conveyed are made possible by the use of micro-structured large mode area single mode fibers (LMA).

Coupling of these components and mastering of the fibered architectures for achieving efficient and compact blue sources tailored to the needs of the market, are the subject of the project.
