The Power of The New ACE Thulium Fiber Laser and Surgical Fiber Assemblies from Coherent
October 21, 2025 by Coherent
In the rapidly evolving landscape of medical technology, innovation continues to pave the way for safer, faster, and more effective patient care. A significant leap forward has been made with the introduction of the new ACE FL Thulium fiber laser (TFL) from Coherent and its accompanying catheter fiber products. This powerful combination is set to redefine numerous medical procedures, particularly in the field of urology, offering unparalleled precision, efficiency, and patient benefits.
What Makes the ACE FL Thulium Fiber Laser a Game-Changer?
The ACE FL series represents a next-generation TFL platform specifically engineered to meet the demanding requirements of various therapeutic medical applications. Unlike traditional laser systems, the ACE FL leverages thulium-doped silica fiber as its active laser medium, emitting light at a precise 1,940 nanometer (nm) wavelength. This wavelength is highly absorbed by water, which is a primary component of both soft tissue and renal systems, making it exceptionally effective for a range of surgical interventions. Latest generation TFL such as ACE FL are rapidly replacing Holmium:YAG lasers due to their higher efficiency, superior precision, and improved water absorption, enabling more effective and safer tissue ablation.
Here's why the ACE FL stands out:
Superior Precision and Control: The TFL's optimal wavelength and advanced optical design provide higher peak power for surgeons with exceptional precision for stone dusting and superior control in tissue ablation. This means more targeted treatment, minimizing or eliminating impact on surrounding healthy tissues.
Operational Advantages for Healthcare Providers: Beyond patient benefits, the ACE FL offers significant advantages for medical facilities. It boasts improved thermal and power management, reduced power draw, and a compact, air-cooled design that ensures ultra-low noise operation. These features translate to lower operational costs, enhanced device longevity, and a more comfortable environment for both surgeons and patients in the operating room. Its ease of integration into existing surgical systems is also a major plus for OEM partners.
Effective Soft Tissue Treatment: The ACE FL is also highly adept at soft tissue applications, particularly in treating conditions like Benign Prostatic Hyperplasia (BPH) or bladder tumours. Its precise tissue ablation and coagulation properties lead to reduced bleeding, less post-operative discomfort, and faster recovery times. The continuous wave (CW) power of up to 250W allows for highly efficient tissue removal.
Enhanced Lithotripsy (Stone Management): For kidney and ureteral stones, the ACE FL offers significantly improved stone fragmentation and dusting capabilities. Compared to legacy Holmium:YAG lasers, the TFL can create finer dust particles (often 10 times smaller), which are easier to pass or suction from the body, leading to higher stone-free rates and potentially reducing the need for retreatment. Its high pulse repetition rate (up to 2,500 Hz) and peak power up to 1.2kW further enhances dusting efficiency.
Minimally Invasive Procedures: The unmatched beam quality of the ACE FL designed to deliver efficient, reliable coupling into smaller catheter fibers. This precision unlocks true minimally invasive procedures and expands versatility across a wide range of clinical applications.
The Power of the Package: Laser and Fiber Assemblies
The ACE FL laser, when paired with our clinically proven portfolio of disposable catheter fiber assemblies, delivers a comprehensive solution that unlocks the full potential of laser-based procedures. These fiber assemblies feature proprietary designs with ultra-high numerical apertures for exceptional bend insensitivity, light capture, and energy delivery.
Engineered with biocompatible coatings and robust, field-tested connectors, they ensure high reliability in clinical environments. A wide range of fiber geometries support varying optical power levels and treatment needs, while specialized distal tip options, from standard polished front emission to side-firing and radial emission, enable a broad spectrum of applications, including prostate treatments, kidney stone removal, soft tissue ablation, and intravenous therapies.
Backed by vertically integrated, cost-effective and highly scalable manufacturing, this delivery system ensures consistent quality, reliable supply, and optimal energy transmission to the treatment site. The synergy between the ACE FL laser and its fiber delivery platform is essential for maximizing clinical outcomes and procedural efficiency.
Looking Ahead
The Coherent ACE FL Thulium fiber laser and catheter assembly platforms are now powering breakthrough research in Urology, Phlebology, and intravascular innovation, pushing the frontiers of minimally invasive care. Its ability to offer superior precision, improved patient outcomes, and enhanced procedural efficiency positions it as a leading technology for a variety of medical procedures. As healthcare continues to shift towards minimally invasive and outpatient procedures, the ACE FL is poised to play a crucial role in delivering safer, faster, and more effective treatments, ultimately improving the quality of life for countless patients.
