Robustness is byword for laser diode modules
Cobolt has announced the release of the Cobolt MLD Series lasers, high performance laser diode modules covering a spectral range between 405 and 660nm. The lasers offer optimum beam quality and modulation performance from a small and compact package. Manufacturing using Cobolt’s HTCure technology ensures excellent quality, reliability and lifetime, as well as unmatched robustness. The lasers provide a spectral complement to the company’s lines of high performance CW DPSS lasers for demanding fluorescence analysis applications such as confocal microscopy and flow cytometry. In addition, the Cobolt MLD lasers have the feature of direct intensity modulation capability, allowing fast and deep modulation from versatile input signals. The selection of wavelengths combined with direct intensity modulation capability make the Cobolt MLD lasers a perfect choice for applications including optogenetics, microlithography or metrology.
Cobolt has designed an easy-to-integrate compact diode laser module with all control electronics fully integrated in a laser head of industry standard size. An optional external control box allows CDRH compliant operation with a key-switch and emission indicators. The Cobolt MLD Series lasers are intended for stand-alone use in laboratory environment, or for integration as an OEM component in analytical or metrology instrumentation equipment.

Solar cells get homogeneous illumination
Limo has announced that its L³ Line Laser generates a very homogeneous illuminated line for scanning a solar cell 156mm by 156mm in size.
The L³ Line Laser’s wavelength of 790 or 808nm makes the spectral separation of the laser beam and photoluminescence signal easier. This property allows photoluminescence to be measured quickly and reliably with the laser illumination. Unlike electro-luminescence

Lasers get US and Canadian safety standard approval
Lasertechnik Berlin has been authorised by Intertek to apply the ETL Listed Mark confirming that LTB’s MNL 300 series lasers have been tested and deemed compliant to US and Canadian product safety standards. The main applications for the lasers are MALDI imaging, fluorescence excitation and the pumping of dye lasers. The MNL 300 lasers are
Bright future for single mode laser diodes
Semiconductor lasers, systems and solutions developer Intense has released a 300mW version of its Series 6030 and Series 6130 ultra high power, high brightness single mode laser diodes.
Designed for defence, medical, and print/ imaging applications such as spectroscopy and industrial coding, the diodes are available in
characterised by a long operational and shelf lifetime, low energy decay and high precision due to the patented sealed cartridge in metal- ceramics technology.
The MNL 300 comes in 20Hz, 50Hz, 80Hz and 300Hz versions. The air-cooled laser is supplied with a low voltage of 24V DC. A wide range power supply (100-240V, 50-60Hz) can be obtained from LTB.

980, 830, 808, 785, and 780nm wavelengths. Custom packaging and wavelengths are available on request. Part of Intense’s Series 6000 family of single mode lasers, the Series 6030 and Series 6130 are based on the company’s patented Quantum Well Intermixing technology, which increases the brightness and reliability of laser diodes while avoiding optical mirror damage.

systems, photoluminescence is a contact- free testing system and thus destruction-free. This measuring method reduces the costs for mechanical setup and prevents damage. At the same time Limo offers beam shaping modules that homogeneously illuminate a complete field under a certain angle. The Fraunhofer Institute for Solar Energy Systems in Freiburg has already tested the interaction between high-performance diode lasers and the beam shaping modules.
