Violino Green (Italian)
532nm laser for micro-material processing
The new end-pumped, Green laser from Laservall: the Violino Green.
Laservall's "Violino Green" is a diode-pumped, Q-switched, air-cooled OEM laser, with a 10W nominal output power, in the single transverse mode (TEM00). The laser emits at the wavelength of 532nm, thanks to frequency doubling (second harmonic generation). The beam is characterized by a high pulse-to-pulse stability (<1.9% at 10W in the Q-switched regime) and high spatial resolution (<30 μm with a 100 mm focal).
