A peak power of more than 0.60MW is generated at 4500 ?, the center wavelength of eoumarin 47. When coumarin 152 is used alone, a broad tuning range of up to 1042 ? has been obtained, which is close to its fluorescence linewidth of 1200 ?.

• Coumarin47染料的中心波长4500?处的峰值功率大于0.；60兆瓦。 仅用Coumarin152一种染料；调谐范围宽达1042?；与其荧光谱线宽度1200?相近。
