The Thulium Duo TFL Laser
A New Benchmark in Urological Laser Lithotripsy and Soft Tissue Surgery
Urology has changed a great deal over the past decade, and few technologies have driven that change as much as fiber laser systems. Holmium:YAG lasers were the workhorse for years, but Thulium Fiber Lasers (TFL) have steadily proven themselves as the more precise, more efficient, and more versatile option for stone treatment and soft tissue procedures alike. The Thulium Duo TFL Laser System is built specifically to meet that shift — combining high peak power, extremely high pulse frequency, and a compact, practical footprint for busy urology departments and outpatient centers.
In this article, we take a closer look at what makes the Thulium Duo a compelling option for urologists evaluating their next laser platform.
Why Thulium Fiber Technology Matters
Thulium fiber lasers operate at a wavelength that is very strongly absorbed by water, which is the primary component of both urinary stones and soft tissue. This translates into several clinically relevant advantages over traditional Ho:YAG systems:
Finer, more controlled ablation with less retropulsion, keeping fragments closer to the treatment site
Reduced thermal spread, which supports safer use near delicate anatomical structures
Smoother continuous or pulsed energy delivery, giving surgeons more flexibility across dusting and fragmentation techniques
Compatibility with smaller-diameter fibers, useful for narrow working channels and flexible ureteroscopy
Thulium Duo: Key Technical Highlights
The Thulium Duo was engineered around the practical needs of the operating room, not just laboratory performance figures. Some of the headline specifications include:
600 W peak power / 60 W average power — enough headroom for demanding fragmentation cases while still allowing fine dusting control
Up to 10,000 Hz pulse frequency — among the highest available on the market, enabling very fine dust-mode lithotripsy with minimal fragment size
1.9 µm wavelength, optimized for water absorption in stone and soft tissue applications
Air-cooled design — no external chiller or dedicated water cooling infrastructure required, simplifying installation and maintenance
Plug-and-play 100–240V operation — suitable for a wide range of facility power configurations without special electrical work
Compact footprint: roughly 43 × 60 × 30 cm and 50 kg, making it easy to position and move between rooms
RFID-based fiber recognition for streamlined, error-resistant setup at the start of each case
3-year full-service warranty as standard, reducing long-term cost-of-ownership concerns
Clinical Applications
The versatility of the Thulium Duo's power and frequency range supports a broad set of urological indications, including:
Ureteroscopic and percutaneous lithotripsy, from dusting to fragmentation-and-extraction techniques
Benign prostatic hyperplasia (BPH) procedures, including enucleation and vaporization approaches
Soft tissue ablation and coagulation in the urinary tract
The high pulse frequency in particular gives surgeons meaningful flexibility to adapt their technique to stone composition and location, rather than being limited to a narrow operating window.
How It Compares to Other TFL Systems
Not all thulium fiber lasers are built the same. One of the most clinically relevant differences between platforms is pulse frequency, since it directly affects how fine a "dust" setting can go and how efficiently larger stones can be broken down. The Thulium Duo's maximum frequency of 10,000 Hz is substantially higher than several established competitor platforms on the market today, which commonly top out at a fraction of that figure. For high-volume stone practices, this difference can translate into shorter operative times and more consistent dust-mode performance.
Designed for Real-World Workflow
Beyond the numbers, the Thulium Duo was designed with everyday clinical workflow in mind. The air-cooled system removes the need for external water cooling infrastructure that many competing platforms still require, which simplifies both initial installation and ongoing maintenance. Its relatively light, compact chassis makes it practical to move between operating rooms or outpatient procedure suites, and the RFID fiber recognition system helps reduce setup errors and turnover time between cases.
A disposable fiber portfolio spans a wide range of core diameters — from 200 µm up to 1000 µm — giving surgeons the flexibility to match fiber choice to the clinical scenario, from flexible ureteroscopy to percutaneous procedures. Reusable fiber options are also in development, aimed at further reducing per-case consumable costs over time.
A Practical Investment for Growing Urology Practices
For hospitals and outpatient centers evaluating a move to thulium fiber technology — or looking to replace an aging Ho:YAG platform — the Thulium Duo offers a combination of high-end performance specifications and practical, low-overhead operation. The 3-year full-service warranty also provides a level of long-term cost predictability that is often a deciding factor for capital equipment purchases.
