Abstract. Application of ultrafast laser treatment of glass-carbon for field-emission cathodes manufacture is considered. The stress-strain state of glass-carbon plate under the action of picosecond laser pulses is analyzed with the use of mathematical simulation.
Keywords: ultrafast laser treatment, glass-carbon, stress-strain state
