MAINZ, Germany, March 12, 2009 – Dilas has launched a family of conduction-cooled high-power fiber-coupled diode laser bars that produce an unpolarized optical output beam.
Within the fiber-coupled architecture, the company uses a polarization scrambler to achieve random polarization. With a degree of polarization of <0.1, the modules are suitable for use by systems integrators in OEM applications, including fiber laser pumping, medical treatments and materials processing.
Standard modules are available with up to 40-W output at 808, 880, 915, 940 and 980 nm, and with a numerical aperture of 0.22 from 400-µm-core fibers.
The devices measure less than 100 × 31 × 20 mm and deliver a wall plug efficiency of >35%. They typically operate at 55 A of current with a compliance voltage of 1.8 V. Standard wavelength tolerances are ±3 nm, and spectral widths are less than 5 nm FWHM. Typical wavelength temperature drift is 0.01 nm per Kelvin.
The sealed housing provides a standard SMA 905 fiber connector, protecting the diode laser bars and the micro-optics against contamination and mechanical damage. The modules are equipped with a second user-exchangeable window for use in harsh environments or in conjunction with disposable fibers.
Available options include an integrated pilot beam, power meter and temperature sensors, as well as fiber detection sensors.
