A single crystal of SrGd(BO) has been successfully grown through a high-temperature solution technique with KO-KF-BO as the flux. It crystallizes in the space group with parameters = 22.3153(5) Å, = 15.

5.32 W ultraviolet laser generation at 266 nm using sum-frequency method with CsBO crystal.

Ultraviolet (UV) beam generation at 266 nm using the sum-frequency (SFG) method with CsBO (CBO) crystals was first suggested in 1997 [Opt. Lett.22, 1840 (1997).

A new praseodymium-based borate crystal PrCaBO (PCB) has been grown through the high temperature solution method. PCB crystallizes in monoclinic space group 2 with unit cell parameters of = 10.9475(10) Å, = 6.

Deep-Ultraviolet Nonlinear Optical Crystal Cs Al (B O ) O: A Benign Member of the Sr Be (BO ) O Family with [Al (B O ) O] Double Layers.

For the explorations of deep ultraviolet (DUV) nonlinear optical (NLO) borates, a type of important optoelectronic material, the (BO ) group has been long regarded as the sole microscopic optically-active unit, and toxic Be-containing raw materials are frequently-adopted. Herein, a new DUV NLO crystal, Cs Al (B O ) O (CABO), was designed and synthesized by simultaneously replacing the (BO ) groups and Be cations for (B O ) units and Al cations in Sr Be (BO ) O, which possesses a favorable structure, through a chemical co-substitution approach. CABO exhibits a considerable DUV NLO capability because of the wide band gap and large birefringence originating from the [Al (B O ) O] double layers.

High-energy noncollinear optical parametric-chirped pulse amplification in LBO at 800 nm.

The optical parametric-chirped pulse amplification (OPCPA) based on large-aperture nonlinear optical crystals is promising for implementation of an ultrahigh peak-power laser system of 10 PW and beyond. We demonstrated the highest energy broadband OPCPA at 800 nm, to the best of our knowledge, by using an 80 mm in diameter LiB(3)O(5)(LBO) amplifier, with an output energy of 28.68 J, a bandwidth of 80 nm (FWHM), and conversion efficiency of 25.
