For the first time, lasing at NV centers in an optically pumped diamond sample is achieved. A nanosecond train of 150-ps 532-nm laser pulses was used to pump the sample. The lasing pulses have central wavelength at 720 nm with a spectrum width of 20 nm, 1-ns duration and total energy around 10 nJ. In a pump-probe scheme, we investigate lasing conditions and gain saturation due to NV ionization and NV concentration growth under high-power laser pulse pumping of diamond crystal.

首次在光泵浦金刚石样品中的NV中心实现了激光发射。使用一列150皮秒、532纳米的纳秒激光脉冲来泵浦样品。激光脉冲的中心波长为720纳米，光谱宽度为20纳米，持续时间为1纳秒，总能量约为10纳焦。在泵浦-探测方案中，我们研究了在金刚石晶体的高功率激光脉冲泵浦下，由于NV电离和NV浓度增长导致的激光发射条件和增益饱和。
