Abstract
An Er:YAG laser at a wavelength of 2.94 μm was simultaneously Q switched and actively mode locked with LiNbO3 as an electro-optic modulator. The modulation crystal was integrated into a specially designed resonance transformer capable of generating a rf voltage of 3 kVpp at a frequency of 160 MHz. Mode-locked pulses with a calculated pulse width ≤ 230 ps were obtained within a Q-switched envelope of 200 ns by applying 16 W of electrical driving power to the resonance transformer during a period of 20 μs.
