[00:00:00]If you shine a strong light on neodymium glass and let the light reflect back and forth between two mirrors to amplify it step by step, it will converge into a highly energetic beam of light. This is a laser. However, when a laser is emitted from a limited aperture, its edges are cut off, forcing it to spread outward. This causes energy dispersion and reduces its destructive power.

[00:00:18]Because you're smart, you attach a telescope to the exit to increase the beam's diameter. The thicker the beam, the smaller the divergence angle caused by diffraction, allowing the laser to travel farther with more concentrated energy. But the enemy can use smoke and anti-laser materials to weaken the laser's effect. So, you install a tunable laser to change the laser's color. By altering the angle or temperature of the internal crystal, you can quickly switch the output wavelength. This helps you find the specific waveband where the enemy's protective coating absorbs the most energy and where smoke interference is relatively weak, effectively breaking through their defenses. To prevent friendly fire, you embed an identify friend or foe IFF module. Using a low-power interrogation signal, it automatically verifies the target before firing. If it detects a friendly signal, it immediately blocks the laser, ensuring absolute safety. However, continuous high-power firing generates massive waste heat. If not removed promptly, the optical components will warp from the heat or even be destroyed.

[00:01:13]Naturally, this doesn't stop you, either. You design a microchannel cold plate that allows the coolant to directly absorb heat from the component's surfaces. A circulation pump keeps the coolant flowing constantly through the pipes, and a heat exchanger dissipates the waste heat into the outside environment, keeping the system running stably for a long time.

[00:01:30]Congratulations, you have invented a laser weapon.
