Everything you Didn’t Know About Infrared Pulse Lasers

Everything you Didn’t Know About Infrared Pulse Lasers

If you didn’t know what infrared pulse lasers are, they can easily be defined as low-cost, high-power lasers with multiple capabilities. The lasers are relatively light and also small in size which makes them ideal for operation without a high input power requirement.

It is important to note that different wavelengths of infrared light have different functions. For instance, Infrared lasers with wavelengths that range between 1310nm, 1550nm, and 1625nm are the best for fiber optic communications, while infrared lasers that have a wavelength of 1480nm function well as pumps for optical amplifiers.

Other Applications of Infrared Lasers

In addition to being used for fiber optic communications, infrared lasers have a host of other applications that cut across various fields and disciplines.

Free Space Optics

Free space optical communication can be defined as the transfer of data between two points with light as the transmission tool. When a laser diode with an infrared wavelength is used in free-space optical communications, the laser light’s invisibility prevents interference and has a low divergence. This means that the light does not spread as it travels. One of the most common applications of infrared lasers under this principle is remote controls. Each remote control has Infrared lasers inside it. These lasers emit binary-encoded pulses to signal when different buttons have been pressed and thus issuing various commands depending on what buttons have been pressed. It is for this reason that there must be a clear path between the remote control and the receiver of the device being controlled for a remote to work. 

In the Military

Infrared lasers are mostly used by the military for targeting. How this works is that every ammunition, for example, gun, comes with a laser pointer that helps the operator of the gun aim for the target. They are especially useful when directing munitions at live targets since light from an infrared laser cannot be seen by the human eye.

Measuring Temperature

Infrared lasers can be used to measure temperature in cases where contact thermometers can be impractical to use. This includes situations such as measuring the temperature of a car’s engine or of food on a grill. How are infrared lasers used to measure temperature? Well, it’s actually quite easy. What you need to do is aim infrared laser light at an object. The light will measure the electromagnetic radiation emitted from the object’s surface and thus be able to tell the temperature.

Medicinal Use

In the medical field, infrared lasers are used in the treatment and reduction of acne, acne scars, wrinkles, and rosacea. These are the most popular targets for non-ablative facial treatments with diode lasers. The lasers are pointed towards the concerned area to destroy the sebaceous glands responsible for oil production. This helps to clear some of the acne thus giving the patient the clear skin they’re after. Other treatment procedures aim for collagen production by intentionally destroying dermis cells. As the cells start to repair themselves, they increase the amount of collagen produced thus giving skin a fuller, healthier look.

Variations of Pulse Laser Diodes

Excelitas offers a range of pulse laser diodes each with different specifications to match different needs. Below are some of the most popular ones.

905nm Generation 2 Triple-Cavity 225 µm Plastic PLD

This 905nm infrared pulse laser uses a multi-layer monolithic chip design. The chip design features an emitting area of (225 x 10) μm by emission of three laser lines. The area is ideal for providing high output power in a small emitting area. In addition to the emitting area, it also has an improved GaAs structure which offers 85 W pulsed peak power when driven at 30 A.

905 nm Triple-Cavity 9 mils SMD PLD

This is an SMD packaged, high efficiency 905 nm pulsed laser diode which comprises of a single stack, triple cavity chip with an impressive 225 µm stripe width. As if that isn’t enough, it provides 70 W at 30 A when tested with a 50 ns wide pulse, and is offered in various other packages.

905nm Triple-Cavity 3 mils metal-can PLD

This is a metal packaged, high efficiency 905 nm pulsed laser diode. It comprises a single stack, triple cavity chip with a 75 µm stripe width. The pulse laser diode provides 24 W at 10 A tested with a 100 ns wide pulse, and just like the SMD packaged one, is offered in various other packages.
