Laser cutting or micromachining is a technology that uses a high-power laser beam to cut a wide range of materials. The materials are burnt, melted, vaporized, or blown away. A computer is used to direct a high power laser for the material to be cut. Once the laser is used on the substrate, it usually melts or burns, and a high-quality surface finish is produced. These are also known as Industrial laser cutters.
There are various kinds of laser cutting methods:
- The Nd-YAG laser utilizes very high energy pulses for cutting, drilling, coring or resizing, trimming, and engraving different materials.
- The CO2 laser is utilized for drilling, cutting, and engraving. It is used for Industrial cutting of material; the CO2 lasers are utilized by Radio Frequency energy or transferring a current through the gas mix.
- The Radio Frequency (RF) method is not prone to problems such as electrode erosion. The gas flow can also affect performance.
- The neodymium Laser (ND): is also used for drilling. But here, high energy pulses are applied using a low repetition speed.
Femtosecond or Picosecond laser micromachining is highly successful because it is a neater, cleaner, and faster way of cutting as compared to the traditional methods of cutting. The laser beams used are precise and quick and is preferred over the traditional methods of cutting as some materials are very difficult to cut. High energy is used to do this specialized way of cutting. Laser micromachining is also the most cost-effective method of cutting high precision parts. It saves time as well since parts do not need to be cut manually.
The amount of cutting power needed for a job depends on the material type, thickness, process used, and desired cutting rate. The advantages of Laser cutting services are that they are ideal for making custom parts quickly and economically. Laser micromachining can be performed on a wide variety of materials and is very successful compared to other forms of cutting.

Lasers have been used as a wide variety of tools since inception, which has enhanced our lives in numerous ways.
The microelectronics, aerospace, medical, solar cell, transducer sensor, display manufacturers, and other fields are the ways lasers are used.Lasers offer precision that was previously inaccessible, even from the most skilled experts.
The relentless pace of progress in high-tech industries has resulted in ultrafast picosecond lasers, which have become valuable tools for, particularly high-precision applications.This is because of the unique operating procedure of this form of laser, which allows patterning and clean cutting of sensitive materials and thin films used in many devices and micromachining of delicate materials such as glass.
This replaces conventional cutting and drilling methods in many applications, reducing the use of other elements.Micromachining silicon solar cellsSolar cell producers are working to achieve grid power cost parity in two ways that reduce the cost of cells and improve the efficiency of cell light conversions.Most solar cells are currently based on silicon wafers, and one way to improve the performance of these crystalline silicon solar cells is to use a backside passivation layer to reduce recombination losses.
Holes must be drilled via the passivation layer to allow electrical contacts to the cell.
To maximize the cell output and ensure good ohmic contact for current collection, this must be achieved with minimal damage to the underlying crystalline silicon.For this mission, picosecond laser micromachining offers a low cost, 'direct-write' alternative to photolithography.
