Ceramic Yb:LuAG gain medium were fabricated and lased in the thin disk architecture. An output power of 1.91 kW was achieved with an optical-to-optical efficiency of 72.2% using a smaller disk while a larger disk achieved an output power of 6.66 kW w

The method based on the generalisation of the phase screen method for a continuous random medium is proposed for simulating numerically the propagation of laser radiation in a turbulent atmosphere with precipitation. In the phase screen model for a d

For solid-state lasers, we have determined that the overlap integrals V/sub th/, related to the threshold pump power, and V/sub slope/, related to the laser slope efficiency, dynamically change with pump power. The increase of diffraction loss is als

Simple stable laser resonators with a single Yb:YAG thin disk module have been designed and demonstrated to produce up to 5 kW CW laser output at 1030 nm with M 2 factor of 7. Pumped with 940 nm diodes, the optical-to-optical efficiencies were >50 %

We have achieved 4.1W of 3.5-micron output from a non-critically phasematched (NCPM), type II, KTiOAsO4 (KTA) optical parametric oscillator (OPO) pumped within the cavity of a Q-switched diode-pumped Nd: YALO laser operating at 10kHz. We adopted the

We generated 110 watts of radial polarized laser beam from Yb fiber laser using photonic-crystal segmented half-wave-plate. This is a promising external radial polarization converter for fiber laser used in the laser cutting industry.

We have demonstrated, for the first time to our knowledge, a coupled tandem optical parametric oscillator (OPO) configuration in which a second ZnGeP(2) OPO is placed within the resonator of the first, KTiOPO(4), OPO. A significant enhancement in the

We report on an intracavity optical parametric oscillator (OPO) placed within a compact diode-pumped Nd:YALO laser cavity. This OPO utilizes a pair of KTP crystals, which are diffusion bonded together in a walk-off-compensated configuration. We have

We present a 120-W cw diode-pumped Tm:YAG laser. The Tm:YAG rod is side pumped by three diode arrays whose radiation is coupled through compound parabolic concentrators. The maximum optical-to-optical conversion efficiency of the 2.02-mum laser outpu
