Innolume solid-state fiber laser (BA)

Innolume's Broad Area Lasers (BA) play a key role in many fields as multimode light sources. They can provide high output power up to tens of watts, with a wavelength range of 1030 nm to 1330 nm, and have a variety of packaging forms, such as Submount, C-mount, TO-can and fiber-coupled packaging, providing diverse choices for different application scenarios.

2. Application Fields

(i) Medical Field

Laser Therapy: In the field of laser therapy, BA lasers can be used for skin treatment

(ii) Industrial Material Processing

Welding, Brazing and Soldering: In the field of industrial manufacturing, the high power output of BA lasers can be used for welding, brazing and soldering processes of metal materials.

(iii) Pumping Solid-State Lasers and Fiber Lasers

Nd:YAG Laser Pumping: BA lasers are often used as pump sources to provide energy for solid-state lasers (such as Nd:YAG lasers) and fiber lasers. In Nd:YAG lasers, the specific wavelength of light emitted by BA lasers is absorbed by Nd:YAG crystals, causing energy level transitions of particles in the crystals, forming a particle population inversion distribution, and thus generating laser oscillation output.

(IV) Sensor field

Gas sensing and perception sensing: In gas sensors, BA lasers can emit light of a specific wavelength. When light interacts with the target gas, gas molecules absorb light of a specific wavelength, causing the laser intensity or wavelength to change. By detecting this change, the gas composition and concentration can be accurately analyzed.

(V) Scientific research

Basic optical research: Provides important light source support for optical research. In experiments studying the interaction between light and matter, the high power and specific wavelength output of BA lasers can simulate different optical environments, helping scientists to deeply explore the optical properties and nonlinear optical effects of materials.

(VI) Wireless energy transmission

Energy transmission medium: In the field of wireless energy transmission, BA lasers can be used as energy carriers to convert electrical energy into laser energy for transmission. In certain specific scenarios, such as wireless power supply between satellites in space or in remote areas, the laser's good directivity and energy concentration characteristics can be used to efficiently transmit energy to the receiving end, which then converts the laser energy into electrical energy for use by the device.

3. Common fault information

(I) Abnormal power output

Reduced output power: After long-term use of the laser, the internal gain medium may age, resulting in a decrease in the ability to amplify light, thereby reducing the output power.

(II) Wavelength drift

Temperature influence: The laser generates heat when it is working. If the heat dissipation system is poor, the laser temperature will rise and the refractive index of the gain medium will change, resulting in wavelength drift.

(III) Reduced beam quality

Optical component problems: Dust, oil or scratches on the surface of the optical component will cause the laser to scatter or refract during transmission, resulting in irregular spot shape and uneven beam energy distribution, thereby reducing the beam quality.

(IV) The laser cannot be started

Power failure: Loose power plug, damaged power cord, burnt components inside the power module, etc., may cause the laser to be unable to obtain normal power and thus unable to start.

IV. Maintenance methods

(I) Regular cleaning

Optical component cleaning: Clean the optical components inside the laser regularly (recommended at least once a week) using professional optical cleaning tools and reagents.

Equipment housing cleaning: Wipe the laser housing with a soft damp cloth to remove dust and stains on the surface to keep the appearance of the equipment neat and tidy.

(II) Temperature control

Cooling system maintenance: Check whether the cooling fan is operating normally, and regularly clean the dust on the fan blades to ensure good heat dissipation.

(III) Regular testing

Power detection: Use a power meter to regularly detect the output power of the laser and establish a power change curve. If the power drops or fluctuates beyond the normal range, please find the cause in time.
