LED Lighting Fixtures公司(LLF)宣布开发出一种LED照明设备原型产品，该产品能提供相当于60W白炽灯的亮度，而功耗仅为16W(前者的27%)。这种照明产品经由可发出753流明白光的独立测试设备检测，交流输入功率为15.9W，该输出相当于47流明/W的亮度。 LED照明的寿命在常规工作条件下比传统照明长十倍，而能耗仅为后者的几分之一，因而具有广阔的发展前景。
Gold nanorods (GNRs) with two different aspect ratios were successfully utilized as saturable absorbers (SAs) in a passively Q-switched neodymium-doped lutetium lithium fluoride (Nd:LLF) laser emitting at 1.34 μm. Based on the GNRs with an aspect rat
A passively Q-switched mode-locked (QML) Tm:LiLuF4 (LLF) laser with a MoS2 saturable absorber (SA) is demonstrated for the first time, to our best knowledge. For the Q-switching mode, the maximum average output power and Q-switched pulse energy are 5
Two-dimensional (2D) graphite carbon nitride (g-C3N4) nanosheets have been successfully used as a saturable absorber (SA) in a passively Q-switched Nd:LLF laser at 1.3 μm for the first time, to the best of our knowledge. Under an incident pump power
