Discussion and research on using high power lasers in the oil, gas, geothermal, and mining markets extends back to the 1960s. Until now the available high power gas lasers required high voltages and precision alignments that made them extremely large, inefficient, and too fragile to transport.

The fiber laser however consists of modular architecture of coupling individual high power laser diodes to an active fiber that is built from the “bottom up” to create higher and higher powers. This architecture gave rise to a logarithmic scaling of cost and power.

Fiber laser costs have dropped from over $1,000/W to less than $50/W in just 15 years.

Over the past decade, advancements in fiber laser technology have increased power availability from less than 1 kW to greater than 50 kW; reduced costs from greater than $1000/W to less than $50/W; and allowed rugged field transportation and operation.

Upon reaching technology critical mass, high-power lasers potentially will have the same type of impact on the oil, gas, geothermal, and mining industries that is occurring in the automotive, manufacturing, defense, and medical industries.

THE EVOLUTION

The experts consensus was that multi-kW, multi-mile high power laser transmission is “impossible”

Stimulated Brillouin Scattering (SBS)

Stimulated Brillouin Scattering (SBS) is a “physics effect” that chokes off the transmission of high power laser photons in a fiber optic cable by reflecting the energy backwards to catastrophically destroy both the fiber optic cable and laser source. In short, photons and acoustic phonons interact in a vicious cycle that gets exponentially worse with increasing power and distance.

Foro Energy started with the three governing equations of SBS to build a foundational physical understanding of the phenomenon and the resulting impact on high power laser transmission.

With advanced physics simulations and experimental capabilities, Foro Energy developed a solution where the fiber optic cable, laser source and combined system are simultaneously engineered to eliminate the onset of Stimulated Brillouin Scattering. This gives us the unique capability to transmit high power lasers in fiber optic cables over long distances.
