At Laser World of Photonics, the Ferdinand-Braun-Institut highlighted its miniaturized laser beam sources which are suitable for a variety of applications, from material processing to display technology.

Compact laser modules from the Berlin-based Ferdinand-Braun-Institut (FBH) which are only the size of a matchbox open up various application areas. The flexible all-rounders can be optimized according to the specific demands made on lasers in material analytics, display technology as well as material processing.

The modules consist of several optoelectronic semiconductor chips (diode laser and amplifier) and adapted gallium nitride transistors. All chips have been developed at FBH and base on the institute's comprehensive know-how in semiconductor technology and chip development. Additionally, hybrid-integrated micro optics and non-linear crystals form the beam and transform the wavelength into the blue and green spectral region respectively. Within this spectral region, the modules now reach output powers exceeding 1.5 W with an excellent beam quality. Using a single-pass configuration enables simple frequency doubling and thus modules which can be realized specifically compact. They are particularly suitable for applications requiring low-noise performance, this means with as little undesired signals as possible, and fast modulation.

Efficient, pulsed laser beam sources offering high flexibility

The FBH additionally presents diode lasers which are, due to their flexibility, preferably used in laser systems for material processing. Mobile short-range LIDAR systems may also benefit from the efficient and compact diode lasers. One of such sources is a newly developed miniaturized pulsed laser module with 10 ps … 100 ns pulse width and a defined repetition rate in the kHz and MHz range. FBH also introduces these lasers at the accompanying symposium. With hybrid-integrated amplifiers they reach peak powers up to several 10 W.

With its gain-switching 1064 nm DFB laser diodes assembled with integrated electronics in a butterfly housing, which FBH showcases at the fair for the first time, the institute introduces further flexible light sources for the 1-100 ns time-domain. Without amplifier, their pulse powers are at 1.5 W in the time range 1-10 ns.
