Article Synopsis
- Researchers studied random lasing from CsPbBr3 quantum dots made using the hot injection method at room temperature, focusing on how film thickness and aggregation affect lasing performance.
- The perovskite exhibited linearly polarized amplified spontaneous emission (ASE) when pumped above a certain energy threshold, demonstrating a gain guiding effect, and produced better image quality than Q-switched Nd:YAG lasers.
- Temperature tests showed that as temperature increased, the ASE photon energy experienced a red shift, suggesting the potential of these perovskite materials for future microcavity laser applications.
Based on cascaded Raman scattering, near-infrared (NIR) noise-like pulses (NLPs) were successfully demonstrated using a Yb-doped fiber amplifier system. Through a nonlinear fiber amplifier using a germanium-zirconia-silica Yb-doped single mode fiber as a gain fiber, the fourth-order Stokes wave (4-SW) can be excited to extend the emission peak of approximately 1.2-µm and a 3-dB bandwidth of approximately 130 nm.
