Laser device for piercing holes in components of a fluid injection device

The device has a laser resonator (4) to generate primary impulsions having duration of microseconds. Modulation units (8) are arranged in between the resonator and a head (24) of the device. The modulation units modulate amplitude of the primary impulsions to supply a set of secondary impulsions. The laser resonator is formed by an active solid atmosphere and optical pumping units.
