Single-shot intense few-cycle pulse interaction with polycrystalline ZnSe

Area of Science:

• Fundamental light-material interactions
• Nonlinear optics in solids
• Optical material science

Background:

• High-intensity few-cycle laser pulses offer novel research avenues.
• Understanding laser-material interactions is crucial for optical design.
• Carrier-envelope-phase (CEP) stability is key for precise laser control.

Purpose of the Study:

• To investigate laser-induced damage on ZnSe using ultrashort, CEP-stable infrared laser pulses.
• To determine the laser-induced damage threshold in a single-pulse regime.
• To characterize the initial laser-induced structures on the ZnSe surface.

Main Methods:

• Irradiation of ZnSe surfaces with 11 fs, two-cycle infrared laser pulses.
• Systematic study of laser-induced damage threshold (1-on-1 regime).
• Characterization of laser damage morphologies using microscopy.

Main Results:

• Demonstrated the earliest stages of laser-induced structures on ZnSe.
• Utilized the shortest available CEP-stable infrared few-cycle laser pulses.
• Established a baseline for laser-induced damage on ZnSe under specific conditions.

Conclusions:

• The study provides insights into the initial phase of laser-matter interaction with ultrashort pulses.
• Findings contribute to the development of high laser light damage resistance in optical components.
• The use of CEP-stable few-cycle pulses enables precise control over laser-induced phenomena.
