Multiradiance: Safe, Proven Cold Laser Systems

Explore the Multiradiance family — TQ Solo, MR4 Activ, and MR4 Pro — and understand why super-pulsed technology has become one of the most trusted approaches in cold laser therapy.

Multiradiance has quietly become the global standard in low-risk, high-efficacy cold laser therapy. With more than 500,000 systems in use worldwide, their devices are known for three things patients and practitioners consistently value: industry-leading safety, extremely simple operation, and research-backed results across hundreds of conditions.

Unlike continuous-wave Class 4 lasers—which can generate heat and require higher clinical oversight—Multiradiance products use super-pulsed 905 nm technology. This creates very high peak power for deep penetration while keeping the average output extremely low. The result: deep tissue activation with essentially zero thermal tissue risk, making these systems ideal for clinics, mobile practitioners, athletes, and home users who want professional-level outcomes without complexity.

Most Popular Home System

TerraQuant TQ Solo

Our most popular home-use cold laser system ever built.

$2,495 (TQ Solo)

The TerraQuant TQ Solo is legendary for one reason: anyone can pick it up and start treating safely in minutes. It combines a 15,000 mW peak-power super-pulsed laser at 905 nm with supporting 875 nm infrared and 660 nm red LEDs, offering a broad therapeutic range without producing heat.

  • Safe, non-invasive pain relief with no risk of burning.
  • Portable, cordless operation for treatment anywhere.
  • Simple one-button use—no menus or complexity.
  • Clinical-grade performance in a compact, user-friendly form.

Sports & Rehab Favorite

MR4 Activ

Handheld, battery-powered system for sports, rehab, and mobile providers.

$7,995 (MR4 Activ)

The MR4 Activ takes everything users love about the TQ Solo and builds on it with professional refinements. Designed for sports medicine and fast-paced rehab, the Activ provides deeper penetration and more flexibility while staying completely non-thermal.

  • 15,000 mW super-pulsed peak power for deep tissue activation.
  • Integrated blue light for skin-level inflammatory or microbial support.
  • Preset treatment modes for fast, repeatable sessions.
  • Cordless, long-runtime operation ideal for sideline or mobile care.

Clinic Workstation

MR4 Pro

Upgradeable desktop console for high-volume clinics.

$6,995+ (MR4 Pro configurations)

The MR4 Pro is Multiradiance’s core clinical workstation—powerful, flexible, and built for high patient volume. Clinics can start with a single emitter and expand over time with larger heads or additional ports, creating a scalable therapy platform.

  • Up to 25,000–50,000 mW super-pulsed peak power with no heat risk.
  • Dual-port architecture for operating multiple emitters.
  • Preset programs for consistent results across staff.
  • Upgradeable path to LS50, Elite, and LaserStim configurations.

How does Multiradiance technology work?

Multiradiance systems revolve around a super-pulsed 905 nm laser, which delivers very high peak power in ultra-short pulses while keeping the average power extremely low. This allows photons to reach deeper tissues without generating heat. The laser is combined with 875 nm infrared and 660 nm red light, and in some models blue light, creating a layered, multi-depth therapeutic effect.

The goal is to deliver light energy to damaged or stressed tissue, where it is absorbed by mitochondrial chromophores. This supports ATP production, microcirculation, and cellular repair—helping move tissue from a state of damage toward recovery.

What conditions can these systems help with?

Throughout the world, Multiradiance cold laser systems are used to support treatment of:

  • Acute and chronic musculoskeletal pain.
  • Back pain, neck pain, and joint pain.
  • Arthritis, bursitis, tendonitis, and repetitive strain.
  • Soft tissue injuries, sprains, and strains.
  • Post-surgical recovery and sports-related injuries.

Thousands of clinical studies support the use of low-level laser therapy for pain and tissue healing, including double-blind trials specific to TerraQuant/MR4 platforms.

Why choose Multiradiance vs. other cold lasers?

Multiradiance stands out because it solves two key problems in laser therapy:

  • Deep penetration without heat: super-pulsed 905 nm delivers high peak power with low average power, allowing photons to reach deeper tissues while staying non-thermal.
  • Ease of use and repeatability: preset programs, simple interfaces, and non-thermal operation mean any trained staff member—or in the case of the TQ Solo, even home users—can perform consistent, safe treatments.

With more than half a million systems sold, Multiradiance has one of the largest installed bases in the industry, giving it a proven track record in both human and veterinary care.

Which Multiradiance system is right for me?

Choosing the right system depends on how and where you plan to use it:

  • Choose the TQ Solo if you want a simple, affordable, home-friendly system or a portable device for basic pain relief and recovery.
  • Choose the MR4 Activ if you are a clinician, trainer, or mobile provider working with athletes or active patients and want a handheld, professional tool with more flexibility.
  • Choose the MR4 Pro if you run a clinic with higher patient volume and want a scalable workstation that can support multiple emitters and a wide range of musculoskeletal cases.

If you’re unsure, start by clarifying where you will treat (clinic vs. home), how many patients you see, and whether you might want to expand capabilities in the future.
