Which risk increases when a laser cutting system loses collimation?

💡 Explanation

Material dross adhesion rises because power density decreases due to increased beam divergence. Therefore, less material is cleanly vaporized causing it stick, rather than laser becoming more efficient under conditions with diffraction limitations.

• Which risk increases when a cryogenic pump cools liquid helium below its lambda point?
• Which effect will continued application of reverse bias voltage cause in an electrolytic capacitor containing an ionic electrolyte?
• Which failure ensues when a high-power microwave amplifier operates above its designed frequency, while utilizing a resonant cavity?
• Which consequence develops due to spatial and temporal incoherence within a pulsed laser?
• Which risk increases when the electron's energy approaches the Schottky barrier height?
• Which outcome results when applying a strong electric field to a crystalline ionic compound?
