    Opening & Welcome

    0:00

    Lena: Hey everyone, welcome to your personalized podcast from BeFreed! I'm Lena, and I'm here with my co-host Eli, and we are absolutely thrilled to dive into something that's literally shaping our modern world-the physics of lasers.

    0:14

    Eli: That's right, Lena! And you know what's fascinating? We're talking about devices that can cut through steel, perform delicate eye surgery, and even help us understand the fundamental nature of light itself. Today we're going to unpack how these incredible machines actually work at the quantum level.

    0:30

    Lena: Exactly! So whether our listeners are curious about the science behind their laser pointers or wondering how lasers are revolutionizing everything from manufacturing to medicine, we've got them covered.
