Ekspla UAB is manufacturer of advanced lasers, laser systems and optoelectronics.


It has 90 employees, including 13 PhD.


Main products are: solid-state, lamp- and diode-pumped lasers with pulse duration in nano- and picosecond range and harmonics converters, industrial nano- and picosecond lasers with high repetition rate, high power lasers, optical parametric oscillators (lasers with tunable wavelength from 200 nm up to 16 µm), spectroscopic laser systems, including SFG spectrometers for the monolayer and interfaces control and investigations, power supplies, cooling units for lasers and other laser related electronics and optoelectronics.

Research in LAMP

The novel direct laser patterning (DLP) method requires a comprehensive study of laser parameters such as wavelength, pulse duration, repetition rate, pulse energy, exposure time of laser for optimal QDs production. Based on optical properties of the materials, various types of lasers with different pulse duration and wavelength will be applied to initiate optical or thermal transformations in precursors, which then release metal and metal sulphide QD.

2.jpg Laser sources with a tunable wavelength in the mid-IR spectral region developed by Ekspla will be applied in process development to release metallic components of polymeric matrix resonantly, as well.Ekspla will prepare laser source with optimized radiation parameters (power, wavelength, pulsing regimes) as well as the laser processing machine demonstrator including the optimized laser, beam shaping and delivery optics, positioning system in the XY plane with focus adjustment in Z direction.

Based on the parameters optimization obtained by Ekspla, the DLP demonstrator will be implemented directly on the CNR laboratories in order to perform in situ both the device fabrication and the DLP process for the QD-LETs realization.
