Understanding Laser Engraving
Back in the day, engraving was an art practiced by many and was limited to being carried out manually. Early engravers used tools such as chisels to carve out the material and create the desired design. Manual engraving is very limited today. Even if you find a manual engraver, it’s very expensive. Advancements in manual engraving and mechanical techniques have now led to contactless laser engraving.
Laser engraving works on the principle of vaporization. It creates a high-powered laser in a controlled environment. This laser provides an adequate amount of heat that vaporizes the material into fumes and leaves deeply engraved marks. This laser beam acts as a chisel, removing the layer from the material’s surface and incising permanent patterns.
The laser engraving service might be cheaper than manual engraving, but the cost of the laser engraver itself is high. The price of a laser engraver depends on its size, power, and brand. Entry-level engravers start at around $150 and can go up to tens of thousands of dollars.
The idea of customizing various items around you with engraving probably sounds appealing to you, but you may be wondering if you can laser engrave anything.
Almost any material can be personalized using a laser engraver. The only restriction is the size of the item to be engraved. If it’s too little, the laser beam won’t be able to focus on its narrow portions and engrave it properly.
Can You Laser Engrave Gold?
Gold is one of the densest metals, which might not be suitable for engraving by a normal laser engraving system. If you want to engrave gold, the fiber laser system is your best option to carry out the job with high precision without damaging it.
Gold is a metal that does not corrode or tarnish, making it a very appealing material to use. It’s visually pleasing, workable, and has been widely used for making jewelry for thousands of years. Thanks to its unique characteristics and value, gold is a material that holds economic value and is accepted universally as an exchange for goods and services globally.
“But gold shines like fire blazing in the night, supreme of lordly wealth.” – Pindar, Olympian Odes. Gold has been known as a symbol of wealth, mostly used for ornaments and jewelry.
It is molded into various shapes and is available as earrings, necklaces, watches, rings, and every other fashion accessory. Some wealthy people around the world have even wrapped their automobiles in gold as a symbol of their wealth.
When it comes to customization, people prefer to design gold items tailored to their choice. It can be molded into ornaments of various designs. The most common types of customizations used for gold are etching and engraving.
Etching is a process where strong acids are used for printmaking and creating designs on the surface of a metal plate. The acid reacts with the metal’s surface and leaves a permanent mark. Engraving works without using any extra chemicals. It cuts into the material and creates patterns. People are moving more toward engraving due to its ability to create complex designs with minimal room for errors.
Customization can give you a personalized item with your initials on it. Who doesn’t want to surprise their significant other with their initials engraved on a special piece of jewelry, making them feel even more special? Initially, engraving was carried out by hand, but now you can use a laser to engrave your gold items.
It’s important to note that not every type of laser is suitable for engraving gold. As it has a highly reflective surface, one needs a laser with a higher density to work on it.
A pulsed fiber laser is a preferred technology to engrave items made of gold. It has a high-density laser, allowing the material to absorb heat quickly. Its parameters allow it to work in a controlled environment and carry out the engraving on delicate surfaces.
Why Choose Laser Engraving for Gold?
Laser engraving is a highly efficient and precise method for customizing gold items. It offers several benefits over traditional engraving techniques:
- Durability: The engraving is permanent and will not fade, ensuring your designs last a lifetime.
- Precision: Laser engravers can create intricate designs and patterns that are difficult to achieve manually.

Fiber Laser To Laser Engrave Gold
If you tried experiments in school and came across the idea of using a lens and sunlight to start a fire, fiber lasers almost work the same. The lens intensifies the power of sunlight and narrows it down, making it so powerful that it can turn into heat and start a fire.
Fiber lasers use an optical fiber cable made of silica glass that guides the laser more intensely and precisely. This narrowed-down laser beam provides more accuracy, allowing it to work more efficiently in sensitive and small spaces.
The initial cost of a fiber laser machine is high, but it makes up for its price with high performance and ease of access. It has low operating costs that require little or no maintenance and uses up a small amount of electricity to work.
The fiber laser was invented by Elias Snitzer in 1961, and a demonstration of it was displayed to the public in 1963. It wasn’t until the late 1990s that fiber lasers were applied in commercial applications.
