High-Power Semiconductor Laser at 760 Nanometers
Jenoptik is extending its product portfolio for medical applications by including high-power semiconductor lasers emitting at 760 nanometers. This wavelength is used in dermatology and medical hair removal and until now, was only possible to achieve employing alexandrite lasers. The new 760 nanometer semiconductor lasers are efficient, robust, reliable and fully qualified for medical applications. Its laser bars have a fill factor of 30 percent and a 1.5 mm resonator length, providing an optical power of 40 watts at more than 50 percent efficiency (WPE).
At SPIE BiOS, Jenoptik will present beam sources that are based on this new type of semiconductors. They are highly efficient and feature a compact and lightweight design. The semiconductor stacks provide customers with water cooling and a window for easy integration into dermatological handpieces. In addition to this, the new semiconductors are adapted to the pulse lengths and the repetition rates necessary for thermokinetic selectivity and thus for modern epilation.
20-Watt Diode Laser with 1,470 Nanometers Wavelength
Jenoptik has also extended its product portfolio in the area of fiber-coupled diode lasers: Apart from the existing wavelengths from 808 to 976 nanometers, new 1,470-nanometer diode lasers are now available for the customers. These modules have an output power of 20 Watts at 70 Amperes and a high brilliance (400 µm fiber core NA 0.22), making them ideal for applications in endovenous laser treatment. The Jenoptik module offers fiber detection, pilot laser and power monitoring, making it easy to integrate into the end users' devices. At the same time, it is equipped with all the necessary safety features to allow certification in accordance with DIN EN 60825-1.
The redundant, inductive fiber sensors preserve the sensitive surface of the active fiber and thus increase its longevity. In conjunction with a standardized SMA 905 coupling, the customer gets a very versatile module. Its general robustness and longevity are further increased by a tightly fastened fiber adapter that is able to tolerate stress and accidental impacts on the fiber plug occurring in real-life application as a medical laser.
Disk Laser JenLas® D2.mini 8W Including Control Electronics
The proven green disk laser JenLas® D2.mini with an output power of up to 8 W (CW) will also be presented in San Francisco. In order to improve direct integration, the Jenoptik D2.mini-series is now also available in a version including an OEM industrial electronics system or in a compact version that has been tested in accordance with the medical electrical equipment and systems standard DIN EN 6060-1.
The frequency-doubled diode-pumped disk laser is characterized by a high beam quality and a wavelength of 532 nanometers. In addition to the increased power, the OEM design and the small overall size allow for easy integration in various laser-based processing systems at the customer’s site and the miniaturization of the end devices.
The JenLas® D2.mini is based on Jenoptik's well-known and reliable JenLas® D2 technology. The laser is primarily used as a beam source in the field of medicine, especially in ophthalmology for retinal photocoagulation, but also in laser endoscopy and dermatology. Apart from medical applications, the laser is also successfully used for laser shows and projections.
