A diode-pumped, passively Q-switched, single-mode Yb:YAG microchip laser with a very low pulse timing jitter has been demonstrated. The laser consists of an Yb:YAG/Cr:YAG diffusion-bonded chip with a separate VBG outcoupler. A -cut for the Cr:YAG was

Laser bulk damage thresholds were measured for both single-crystal YAG and for diffusion-bonded YAG structures using 600 picosecond pulses at 1064 nm. The tested samples included 3-layer sandwich structures with doped cores of various thicknesses. An

Cr 4+ : GSGG has been utilized for the first time to provide a saturable absorber Q -switch for the ruby laser. Single output pulse operation (100 mJ and 27 ns duration) with efficiencies relative to the free-running ruby laser operation of 25–30%

Passive Q switching of a flash-lamp-pumped ruby laser has been demonstrated with a Dy(2+):CaF(2) saturable absorber at room temperature. Typically a single Q-switched pulse of 4.5 mJ and 94 ns was observed. At 694 nm, the ground-state absorption cros

We demonstrate passively Q switched 2% doped Er:YAG laser operation in the eyesafe region with sub 5 nsec pulse widths using Cr 2+ :ZnSe as a saturable absorber. A rod geometry operating in the burst mode and a micro slab geometry operating continuou

Saturable absorber Q-switching of the 1.54 μm Er:glass laser using U4+:SrF2 has been obtained for the first time. Q-switched pulses of 3 mJ, 60 nanoseconds FWHM were achieved using a 2.69 mm thick Q-switch in a 14 cm long flat-flat cavity, with a 3

Laser action at 300K was demonstrated in Er:Y2SiO5 (Er:YOS) using a 1.53μm Er:glass laser pump. A single pulse of less than 300ns (full width half maximum) at 1.633μm was obtained.

Using a U2+:CaF2 passive Q‐switch for the Er:glass laser, 20 ns, 3 mJ pulses were obtained. This is the shortest duration passive Q‐switched pulse obtained for this laser without intracavity focusing and without optical damage. The measured U2+:C

Saturable‐absorber Q switching of an erbium‐doped Y3Al5O12 (YAG) laser at 1.64 μm using U2+:SrF2 and U2+:CaF2 was demonstrated. The Er:YAG was longitudinally pumped using a free‐running 1.534 μm Er:glass laser. Q switched 1.64 μm pulses of 1
