- SLM20-940-20000-QCW-L-263 with a peak output power of 20 kW at 940 nm (laser pulse energy
density up to 3.75 J/cm2, 1.5 ms, 20 Hz), collimated beam divergence - 14x2 degrees (FWHM);
- SLM12-940-50000-Pulse-HD - 50 kW, 940 nm, 20 ns, 10 kHz.
- laser beam homogenizer based on a two-sided array of perpendicularly arranged cylindrical microlenses made of optical quartz glass, with an aperture of 90x90 mm and a transmission of 99%;
A high-power diode laser is produced - PLD-6 type - provides an output optical power of laser up to 6 kW in CW mode on and a rectangular laser spot 22x2 mm in size at the focus, it is successfully used for laser thermal hardening, alloying and surfacing.
Experimental work has been carried out on the automated laying of a prepreg tape made of thermoplastic materials with local heating of the surface by a powerful diode laser, a technology that is promising for mass production of composite products.
