Title: Self-cavity lasing in optically pumped single crystals of p-sexiphenyl

Abstract

Organic single-crystal self-cavities are prepared by solution growth of p-sexiphenyl (p-6P). Based on Fabry-Pérot feedback inside a quasi-lozenge-shaped platelet crystal, edge-emitting laser is obtained under optical pumping. The multimode lasing band appears at the 0-1 or 0-2 vibronic progressions depending on the excitation conditions which affect the self-absorption effect. Cavity-size dependence of amplified spontaneous emission (ASE) is investigated with laser-etched single crystals of p-6P. As the cavity length of square-shaped crystal is reduced from 100 to 10 μm, ASE threshold fluence is decreased probably due to size-dependent light confinement in the crystal cavity.

  • A simple “cast-capping” method is adopted to prepare single-crystal perovskites of methyl ammonium lead bromide (CH{sub 3}NH{sub 3}PbBr{sub 3}). By capping a CH{sub 3}NH{sub 3}PbBr{sub 3} solution casted on one substrate with another substrate such as glass, mica, and distributed Bragg reflector (DBR), the slow evaporation of solvent enables large-size cubic crystals to grow between the two substrates. Under optical pumping, edge-emitting lasing is observed based on Fabry–Pérot resonation between parallel side facets of a strip-shaped crystal typically with a lateral cavity length of a few tens of μm. On the other hand, vertical-cavity surface-emitting lasing (VCSEL) is obtained frommore » a planar crystal grown between two DBRs with a cavity thickness of a few μm. Simultaneous detection of those edge- and surface-emissions reveals that the threshold excitation fluence of VCSEL is higher than that of the edge-emitting lasing due to thickness gradient in the planar crystal.« less
  • We study the self-organizing properties of an optically driven semiconductor microresonator especially designed and optimized for optical pumping wherein patterns and cavity solitons are observed for the first time with all-optical excitations. We demonstrate both coherent and incoherent writing and erasure of cavity solitons achievable on the same sample, enriching the spectrum of the system functionalities. Finally, we show how the system lends itself to the multiplication of the number of cavity solitons and how they possibly coexist.
  • The action of subnanosecond high-voltage pulses (U = 50-200 kV, t{sub p} = 100-500 ps) on 1-2-mm-thick plane-parallel ZnSe plates is studied. A sample was placed between a cathode and a circular anode. A discharge propagated along the lines of force of the electric field. Lasing at 480 nm appeared at the discharge front and opposite to the cathode. The average propagation velocity of the discharge achieved 5x10{sup 8} cm s{sup -1}, the pulse power was 600 W, and the radiation divergence did not exceed 2-3 deg. No streamer discharges oriented along crystallographic directions were observed. (lasers)
  • Single crystals of solid solutions of a high optical quality are grown in the concentration vicinity of the saddle point of the ternary CaF{sub 2}-SrF{sub 2}-YbF{sub 3} system. Efficient lasing with a small Stokes shift (at 1025 nm) was obtained in 980-nm diode-pumped single crystals. The total lasing efficiency (with respect to the absorbed average pump power) was 59% and the slope efficiency was 83%.

  • Optically induced dynamic nuclear polarization in CdS (resistivity 1.8{times}10{sup 10} {Omega} cm, dark) is observed by radio-frequency detection of the {sup 113}Cd nuclear magnetic resonance signal. At 2 K, the nuclear-spin transitions are emissive when compared to the thermal polarization, and no dependence on the helicity of the pumping light is observed. {copyright} {ital 1999} {ital The American Physical Society}
