Physicsof laser

Depending on various laser parameters and tissue characteristics, we can achieve different effects, including specific distribution of light and heat, chemical reaction, material ablation, ionization or shockwaves. Provided that, there are numerous medical applications of lasers such as biomodulation, photodynamic therapy (allows for fluorescent imaging of tumors located in the urinary tract and performance of more accurate biopsies), coagulation, vaporization (e.g. of prostate neoplasia), fusion, ablation, disruption and fragmentation (used for ureteric and kidney stone management). Urology is a highly demanding, challenging and dynamically developing field of medicine, hence it is paramount that urologists rely on adaptable and modifiable lasers. Different clinical scenarios usually require easily adjustable device settings such as pulse energies, pulse lengths and emitted frequencies. However, it should be highlighted that laser systems can cause serious complications and damage if used improperly. Therefore a laser system has to be intuitively modifiable according to the intended procedure.Don't forget that light could be dangerous - use the technology in an appropriate way.

Decades of successful therapeutic use in urology have established lasers as an extremely valuable tool. Innovative features and solutions are further expanding their clinical applications.

Laser technology is based on the ability of a device to emit a narrow beam of highly focused light. In each LASER (Light Amplification by Stimulated Emission of Radiation) system, the laser medium defines the wavelength. Parallel radiation coming out from the device is easy to focus on a target due to its small focus and high intensity.
