Experimental Study of a Flash-lamp Pumped Passively Q-Switched Nd:YAG Laser Using Cr4+:YAG Saturable Absorber
This paper deals with the experimental results of a xenon flash-lamp pumped passively Q-switched Nd:YAG laser using Cr4+:YAG saturable absorber. The need of a laser cavity to be integrated into a time-of-flight laser range finder is of great interest as an experimental investigation of several laser resonators. Two types of laser resonator, with different lengths, have been studied: the flat-fl...
متن کاملSimultaneous Mode Locking in a Diode-Pumped Passively Q-Switched Nd:YVO(4) Laser with a GaAs Saturable Absorber.
Simultaneous mode locking and Q switching is accomplished in a diode-pumped Nd:YVO(4)/GaAs laser. The average output power is ~2.0 W at 10.6-W absorbed pump power, and the repetition rate of the Q-switched pulse is ~120 kHz. The mode-locked pulse inside the Q-switched pulse has a repetition rate of ~148 MHz, and its average duration is estimated to be ~100 ps.
متن کاملPassively Q-switched diode-pumped Cr:YAG/Nd:GdVO4 monolithic microchip laser
the realization of high repetition rate passively Q-switched monolithic microlaser is a challenge since a decade. To achieve this goal, we report here on the first passively Q-switched diode-pumped microchip laser based on the association of a Nd:GdVO4 crystal and a Cr:YAG saturable absorber. The monolithic design consists of 1 mm long 1% doped Nd:GdVO4 optically contacted on a 0.4 mm long Cr:Y...
متن کاملPassively Q-switched diode-pumped Er:YAG solid-state laser.
We demonstrated laser operation of a passively Q-switched diode-pumped Er:YAG solid-state laser emitting at 1645 or 1617 nm depending on the initial transmission of the Cr:ZnSe saturable absorber. The crystal emitted up to 10 W at 1645 nm and up to 8 W at 1617 nm in CW mode while pumped with 65 W of incident pump power at 1533 nm. In passive Q-switched mode with 40 W of incident power, a Cr:ZnS...
متن کاملDiode edge-pumped passively Q-switched microchip laser
There is an increasing demand for high-intensity subnanosecond lasers for emerging industrial applications. While femtosecond and picosecond laser sources are considered promising, they suffer from the significant drawbacks of increased complexity and cost. In this regard, we demonstrate a unique edge-pumped passively Q-switched Nd∶YAG∕Cr4þ∶YAG microchip laser. The microchip is made of a Nd∶YAG...
