Using lasers in surgery requires a beam to be focused on a very limited area. This ensures the surrounding tissues will not be damaged, which will ultimately lead to a faster recovery compared to other conventional methods. To achieve this, suitable optics with high damage threshold coatings at critical wavelengths are a crucial requirement.
Superficial cutting and ablation in laser surgery are typically achieved with a Holmium: YAG laser.
The wavelength of the Ho:YAG laser-beam is highly absorbed by water, a primary component of all human tissues, organs, and cells.
As a result, the Ho:YAG laser has become widely adopted in many medical settings, perhaps most notably in urology for procedures including incision of urethral and ureteral structures, and lithotripsy to break stones located in the urinary tract.
To provide accurate and clean incision at high speed, leading to reduced operating times, indestructible optical components must be part of such laser systems.
For such critical applications, Altechna offers high-repeatability optics and sub-assemblies, characterized by a high LIDT of >30 J/cm2 @ 2090 nm, 10 ns, and low absorption coatings.
The following whitepapers on 2 µm applications, low absorption coatings for CW regimes, and the Altechna brochure on assembly capabilities offer crucial information about these advanced solutions.
