As a safe, reliable, and strongly electromagnetic resistant initiation method, laser initiation shows great promise in military blasting applications. Many obstacles exist when delivering a high-energy laser through optical fibers, directly influencing the energetic explosives under low-initiation conditions. Herein, we developed silver nanoplates as a laser energy absorber to reduce the laser initiation threshold and delay time. During the growth process of the silver seed nanoplates, mechanical disturbance was applied to provoke the nanoplates to develop more internal hotspots. Meanwhile, in ultraviolet visible near-infrared (UV–VIS-NIR) testing, the absorption peak was regulated to 808 nm by tailoring the size of the nanoplates. Results showed that the maximum temperature of the cracking nanoplates could reach 100 °C within 10 s, under the irradiation of an 808 nm diode laser at a power density of 1 W·cm⁻². Through their use as a laser energy absorber, the silver nanoplates can effectively reduce the initiation threshold of cyclotrimethy lenetrinitramine (RDX) by 58.33% and reduce the delay time of B/KNO₃ by 51.00%. This result provides potential applications for initiation energetic explosives at low laser energy.

作为一种安全，可靠且抗电磁干扰的启动方法，激光启动在军事爆炸应用中显示出巨大的希望。通过光纤传送高能激光时，在低起爆条件下直接影响高能炸药时存在许多障碍。在本文中，我们开发了银纳米板作为激光能量吸收剂，以降低激光启动阈值和延迟时间。在银种子纳米板的生长过程中，施加机械干扰来激发纳米板以产生更多的内部热点。同时，在紫外可见近红外（UV-VIS-NIR）测试中，通过调整纳米板的尺寸将吸收峰调节至808 nm。结果表明，开裂的纳米板的最高温度可在10 s内达到100°C，⁻²。通过将其用作激光能量吸收剂，银纳米板可以有效地降低环三甲基lenetrinitramine（RDX）的起始阈值58.33％，并减少B / KNO ₃的延迟时间51.00％。该结果提供了在低激光能量下引发高能炸药的潜在应用。
