The RPK445M is a high-power, multi-mode OEM laser diode.  This fiber-coupled, 445nm diode laser offers up to 50W of continuous wave (CW) output from a 105-micron core diameter pigtailed fiber optic cable, terminated with a SMA905 connector.  This diode utilizes proprietary fiber-coupling techniques, resulting in volume products with high efficiency, stability, and superior beam quality. This 445nm laser achieves the high-quality beam by transforming the asymmetric radiation from the laser diode chip into an output fiber with a small core diameter by using special micro-optics, resulting in exceptional brightness.  Additionally, these diode lasers go through an extensive inspection and burn-in procedures at each step of the production process, ensuring reliability, stability, and lifetime.

RPMC provides a complete, turn-key laser diode system option for the RPK Series, suitable for material processing, medical therapeutics, and pumping solid-state laser media. Delivering up to 200W of diode laser into a 100~400um core fiber, the system makes it easy to develop new applications. The Turn-Key Laser Diode System is available in the following wavelengths: 450nm, 635mn, 660nm, 680nm, 690nm, 793nm, 808nm, 830nm, 9xxnm, 1470nm, 1550nm. Other wavelengths are available upon request. With control over the operating temperature of the diode laser, as well as current and pulse width, the system offers flexibility and an easy-to-use interface. The system can be controlled either by the front panel user interface or by a computer-controlled RS-232 interface.

RDS3 Features:

  • Up to 200W output power
  • Select from 11 standard wavelengths
  • Other wavelengths available upon request
  • Air cooling
  • Fiber delivery
  • Temperature control
  • Red aiming beam (optional)
