“…The challenge with conventional SPLs is that the pump light source, sunlight, is incoherent white light that requires tight focusing to achieve sufficient population inversion in the laser medium. For this reason, all SPLs published to date have relied on a primary concentrator comprised of a large lens or mirror [15]. In turn, this requires precise tracking of the sun to maintain illumination of the laser medium [16].…”

We have developed a fully planar solar-pumped fiber laser using a solid-state luminescent solar collector (LSC). This laser does not use any focusing device, such as a lens or mirror; thus, it can lase without tracking the sun. Our developed device with an aperture of 30 cm emits 15 mW, corresponding to an optical-to-optical conversion efficiency of 0.023% and a collection efficiency of 0.21 W/m2. A 12-fold improvement over a previously developed liquid LSC is achieved by combining the total internal reflection of the solid-state LSC with dielectric multilayer mirrors. The observed laser power is in good agreement with that predicted via numerical simulation, demonstrating the effectiveness of our proposed method.

“…In order to improve the performance of lasers, we first used highquality Nd:BGO crystal grown by the micro-pulling-down method as the gain medium. Moreover, the thermal effect of the laser crystal affects the threshold power, slope efficiency, beam quality and so on [13,14]. Therefore, we used the direct pumping technique at 880 nm to decrease the thermal effect.…”

Indium tin oxide nanocolumns array (ITO-NCs-A), a typical epsilon-near-zero material, was prepared by chemical vapor deposition method. Due to the strong third-order optical nonlinearity and large refractive index change of the ITO-NCs-A at ~1.06 µm, we used it as a passively Q-switched device and obtained a stable 1.06 µm Nd:BGO pulsed laser for the first time, to the best of our knowledge. The maximum average output power is 152 mW, the maximum repetition rate is 126.1 kHz, the shortest pulse width is 579.6 ns, and the corresponding single pulse energy and pulse peak power are 1.21 µJ and 2.08 W, respectively. This work indicates that ITO-NCs-A has promising applications in ultrafast photonics and is expected to provide a more reliable solution for optical modulators in pulsed lasers.
