Diode-Pumped Thin-Disk Lasers

Product catalog summary

Overview: The JenLas® D2.mini series consists of diode-pumped thin-disk lasers with frequency doubling, designed for compact device integration. They are noted for their small size, low heat output, and minimal cooling needs, making them suitable for fields such as ophthalmology, dermatology, entertainment, and spectroscopy.

Specifications: These lasers provide continuous wave output power from 2 W to 8 W at a wavelength of 532 nm. They feature a beam quality of M² < 5 and a beam diameter of approximately 1.5 mm. Operating conditions include ambient temperatures from 5 °C to 40 °C and relative humidity from 5% to 90% (non-condensing). Electrical input requirements vary, with up to 35 A at 2 V needed.

Mechanical Properties: Laser module dimensions vary slightly with power output, weighing between 0.345 kg and 0.5 kg. Optional features include a fiber coupling unit with an SMA connector for 100 µm fiber-core, aiming beam, and redundant power monitoring.

Safety and Compliance: Classified as Class 4 laser products under EN 60 825-1: 2007, these lasers emit invisible radiation that can be hazardous to eyes and skin.

Applications: Suitable for medical procedures like retinal photocoagulation and dermatological treatments, as well as industrial applications such as pumping of Ti:Sa lasers and illumination.

Additional Features: Designed for easy integration with OEM systems, featuring high beam quality and Peltier cooling, eliminating the need for water cooling.

General Properties of JenLas® femto Lasers: Available in femto 10 and femto 16 models, offering IR and SHG options with wavelengths of 1030 nm and 515 nm. The femto 10 model provides ≥ 10 W (IR) and ≥ 5 W (SHG), while femto 16 offers ≥ 16 W (IR) and ≥ 8 W (SHG). They feature a beam diameter of 1.2 mm (IR) and 0.8 mm (SHG), with a pulse repetition rate from single shot to 510 kHz, and a typical pulse width of 550 fs ± 150 fs.

Electrical and Mechanical Properties: Requires a power supply of 110 – 240 V AC (50/60 Hz) with a maximum power consumption of ≤ 1 kVA. The chiller requires (208)/230 V AC (50/60 Hz) with ≤ 2.2 kVA. The laser head dimensions are 500 mm x 273 mm x 968 mm, weighing 100 kg plus a 15 kg base plate.

Safety and Compliance: Classified as Class 4 laser products under EN 60 825-1: 2007, requiring precautions to avoid exposure to direct or scattered radiation.

Application Examples: Suitable for precision micro-drilling in stainless steel, engraving micro channels in glass, and cutting microstructures in bio-resorbable polymers without causing micro-cracks or debris.

JenLas® Disk Lasers: The JenLas® disk IR50, IR70, and IR70E are nanosecond disk lasers with high peak power, offering maximum output powers of 45 W, 65 W, and 65 W, respectively. They provide pulse energies up to 7 mJ and peak powers up to 217 kW, designed for high productivity and quality micro machining with minimal heat-affected zones.

Applications: Used for precise micro-processing, including micro-drilling, cutting, and structuring of hard and brittle materials like SiC, WC, PCD, and highly heat-conductive materials like Cu, Al, or Ti, as well as composite materials like CFRP.
