The Ferdinand-Braun-Institut (FBH) demonstrated its compact laser beam sources that are ideal for numerous applications ranging from display technology to material processing at the Laser World of Photonics, which is being conducted from 23 to 26 May 2011 in Munich, Germany.
Compact Laser Module
The small laser modules comprise numerous gallium nitride transistors and optoelectronic semiconductor chips such as amplifiers and diode lasers. The FBH develops those chips using its extensive expertise in chip engineering and semiconductor technology. Moreover, non-linear crystals and hybrid-incorporated micro optics create the beam and change the wavelength into the green and blue spectrum, respectively. Inside this spectral range, the laser modules now realize over 1.5 W of output powers with a superior quality of beam.
The utilization of a single-pass pattern allows the doubling of simple frequency, resulting in particularly compact laser modules. Due to their rapid modulation and low undesired signals, these modules are specifically ideal for applications demanding low-noise performance.
The FBH also displays its highly efficient, flexible and compact diode lasers that are ideal for laser solutions employed for material processing and mobile short-range LIDAR systems. One among such laser sources is a new compact pulsed laser module with a known repetition rate ranging from kHz to MHz and pulse width range between 10 ps and 100 ns. These lasers can attain optimum powers of as high as numerous 10 W by utilizing the hybrid-incorporated amplifiers.
The FBH exhibits highly versatile light sources within in the 1-100 ns time range for the first time at the fair. They are configured in a butterfly package with incorporated electronics and gain-switching 1064 nm DFB laser diodes. Devoid of amplifier, the light sources have 1.5 W of pulse powers in the 1-10 ns time range.
