Embodiment 1
[0028] A Nd:YAG all-solid-state continuous laser with a wavelength of 1064nm is used to preheat the mixed gas with an output of 50W laser. Subsequently, the mixed gas was ignited by a 532nm green nanosecond laser with a repetition rate of 10Hz and a single pulse energy of 100mJ.
[0029] The laser ignition operation according to this embodiment is completed under the above conditions, and the ignition of the mixture of methane and air is realized.
Embodiment 2
[0031] Using CO 2 Continuous laser with a wavelength of 10.6um, which outputs 150W laser to preheat the mixed gas. The mixed gas is ignited by a picosecond laser with a wavelength of 1064 nm, a repetition rate of 10 kHz, and a single pulse energy of 0.5 mJ.
[0032] The laser ignition operation according to this embodiment is completed under the above conditions, and the ignition of the mixture of methane and air is realized.
