Introduction — How Lasers Revolutionized Modern Technology?

Lasers were once a lab curiosity. Today, they are everywhere, from manufacturing lines to medical rooms.

The invention of lasers opened up new possibilities in precision, speed, and material processing that traditional tools could never achieve.

From barcode scanners to satellite systems, lasers are essential tools across industries.

How They Work: Crystals doped with rare-earth ions (예를 들어, Nd:야그, Nd:Glass)

주요 특징: 높은 전력, strong pulse energy

응용 프로그램: Cutting, drilling, medical surgery, and defense systems

The Six Main Types of Lasers Explained?

Even with the same beam, no two lasers are created equal.

Each laser type operates on a different principle and excels in specific domains. Knowing the differences is critical for effective application.

Let’s explore what sets each laser type apart, starting from the most common in industry.

1. Solid-State Lasers¹

Lasers like Nd:YAG use a solid crystal as their gain medium, energized by a light source.

They deliver high pulse energy and power, making them suitable for heavy-duty tasks like cutting and defense.

Use Cases and Considerations

• Material Processing: Efficient in metals and ceramics

• Medical Use: Eye surgeries, tattoo removal

• 단점: Requires cooling, sensitive to thermal load

파장	1064 nm (common)
빔 품질	높은
Cooling Needs	높은
능률	중간

2. Fiber Lasers²

These use doped optical fibers and are highly efficient and compact.

Fiber lasers offer excellent beam quality and are ideal for precision tasks in tough environments.

Why Industry Prefers Them

• Cutting & Welding: Especially with reflective metals like copper

• Communications: Telecom-grade reliability

• 유지: Minimal due to sealed structure

3. Gas Lasers³

Relying on gas discharge tubes, they deliver stable output in visible to IR spectra.

Gas lasers remain staples in engraving and scientific setups due to their wavelength stability.

Popular Variants
