A scheme of plasma–chemical mid-IR hydrogen fluoride (HF) lasing is proposed, in which electrons of femtosecond filament are produced in argon and give rise to a chain of plasma–chemical reactions occurring with SF 6 and H 2 added to the argon bath and resulting in the formation of vibrationally excited HF molecules. The conditions for the occurrence of amplified spontaneous emission and lasing in the range of 2.7–3 μ m in a selected gas mixture at a total pressure of several atmospheres can be realized under the action of a femtosecond laser on Cr-forsterite with a wavelength of 1.24 μ m. In numerical experiments, it was demonstrated that HF lasing energy at the level of 1.5 μ J are achievable for typical monofilament plasma parameters.

在高压混合物SF 6 -H 2 -Ar中等离子体化学反应下，飞秒灯丝驱动的中红外激光发射

提出了等离子体化学中红外氟化氢（HF）激光发射的方案，其中飞秒灯丝的电子在氩气中产生，并导致在氩气中加入SF 6和H 2时发生的一系列等离子体化学反应浴并导致振动激发的HF分子的形成。在飞秒激光作用于铬镁橄榄石上的飞秒激光的作用下，可以实现在几种气体的总压力下，在选定的混合气体中发生自发发射和激射的放大条件，范围为2.7–3μm。 1.24微米 在数值实验中，证明了典型的单丝血浆参数可以达到1.5μJ的HF激光能量。
