Pet laser therapy, as a non-invasive treatment method, has gained wide recognition in the veterinary field in recent years. This technology uses light energy of specific wavelengths (650nm, 808nm, 910nm, 980nm, and 1064nm) to act on the affected area, providing a safe and effective treatment option for pets. This article will delve into the unique advantages of different wavelengths of lasers and their application value in clinical practice.

The Mechanism of Laser Therapy

The working principle of pet lasers is based on photobiomodulation. When light of specific wavelengths penetrates tissues, it is absorbed by cytochrome c oxidase in the mitochondria of cells, thereby:

1. Promoting ATP energy synthesis

2. Improving local microcirculation

3. Reducing inflammatory responses

4. Accelerating tissue repair

Clinical Application Characteristics of Different Wavelengths

650nm (Visible Red Light)

• Tissue penetration depth: 0.5-2cm

• Best indications:

– Superficial wound healing

– Skin ulcers

– Postoperative incision care

• Therapeutic advantages: Significantly promotes epithelial cell regeneration

808nm (Near-Infrared Light)

• Tissue penetration depth: 3-5cm

• Best indications:

– Muscle strains

– Arthritis

– Tendinitis

• Clinical value: The most commonly used treatment wavelength by veterinarians

910nm (Near-Infrared Light)

• Unique advantages:

– Special water absorption characteristics

– Promoting lymphatic circulation

– Reducing tissue edema

• Typical application: Postoperative swelling management

980nm (Near-Infrared Light)

• Deep treatment characteristics:

– Can reach the depth of joint cavities

– Effectively alleviates deep pain

• Combined application: Often used in conjunction with 808nm

1064nm (Infrared Light)

• Deep penetration ability:

– Can reach up to 7-8cm

– Reaches the surface of bones

• Special applications:

– Hip dysplasia

– Spinal disorders

– Chronic pain management

Multi-wavelength pet laser therapy technology has brought revolutionary changes to modern veterinary practice. Modern pet laser therapy devices mostly adopt multi-wavelength combination technology, with advantages including:

1. 650nm + 808nm combination: Balancing superficial and medium-depth treatments.

2. 808nm + 980nm combination: Optimizing the therapeutic effect for musculoskeletal diseases.

3. Sequential multi-wavelength treatment: Achieving full-layer tissue repair.

Clinical treatment guidelines

To ensure treatment efficacy and safety, the following should be noted:

• Treatment dose: 4-10 J/cm²

• Treatment frequency: Once daily during the acute phase, and 2-3 times weekly during the chronic phase.

• Treatment course: Usually 6-10 sessions constitute a complete course.

• Safety precautions: Operators must wear specialized protective glasses.

Summary of treatment advantages

Compared with traditional therapies, pet laser therapy offers:

✓ Non-invasive and painless experience

✓ No drug side effects

✓ Short treatment time (5-15 minutes per session)

✓ Wide application range (dogs, cats, exotic pets, etc.)

✓ Can be combined with other therapies

Future development trends

With technological advancements, pet laser therapy is moving towards the following directions:

• Intelligent parameter adjustment systems

• More precise wavelength combination schemes

• Development of portable home-use devices

• Quantitative assessment of treatment effects

RealLight‘s single-wavelength and multi-wavelength modules are high-performance light sources designed for laser pet physiotherapy devices, providing precise laser energy output. By scientifically selecting laser wavelengths from 650nm to 1064nm, veterinarians can offer precise and safe treatment plans for pets. This non-pharmaceutical therapy not only enhances treatment effectiveness but also significantly improves the quality of life for sick animals, representing an important development direction for future pet healthcare.
