- New blue laser diode from ams OSRAM enables Convergent Photonics to mount micro-optics close to laser facet to give excellent control of beam shape and size
- Specialist manufacturer Convergent Photonics uses chip-on-submount products to increase optical power and reduce size of laser modules for welding equipment and advanced surgical instruments
- ams OSRAM’s blue laser diode in chip-on-submount format provides compact alternative to familiar TO can package
Convergent Photonics, based in Torino, Italy, is now taking advantage of ams OSRAM´s blue laser diodes in a CoS format to produce new, highly efficient and extremely compact multi-emitter laser modules with micro-optic lenses emitting in the visible wavelength range at 445 nm.
The CoS packaged laser diodes offer a compact alternative to the familiar TO can. Several CoS lasers can be combined in one module to save space. For this, micro-optic lenses are mounted adjacent to the laser facet, which enables the coupling of the single lasers into optical fiber, and thus giving much more precise control of beam shape and size. This compact modular design also enables better thermal management than systems based on lasers in the TO format.
ams OSRAM supplies blue CoS lasers in two versions, both of which have a power output of 5W: the 1.0mm x 1.3mm x 0.2mm PLPCOS 450D, and the 4.0mm x 3.0mm x 0.3mm PLPCOS 450E, which is mounted on a thermally efficient direct bonded copper (DBC) substrate.
Coupled to 100µm optical fiber with optical power output of up to 100W, the Convergent Photonics multi-emitter laser modules can be combined to further scale up power, providing a very compact solution for welding equipment.
For medical applications, the same technology - also combining multiple blue CoS lasers from ams OSRAM – is integrated with control electronics to provide a very compact stand-alone source. Moreover, combining it with different wavelengths, Convergent Photonics provides a family of hybrid multi-wavelength sources, all packaged in a single compact module, for use in advanced surgical equipment.
‘Conventional package styles for blue laser diodes limited our scope to incorporate blue light into our portfolio of compact, efficient laser modules. With ams OSRAM’s development of a chip-on-submount blue laser, we now have a building block which can be scaled up to support high-power applications in a very compact assembly,’ said Roberto Paoletti, Director of Diode Fab at Convergent Photonics. ‘Now we can incorporate blue laser emission in modules which match the excellent size, weight and power characteristics of our existing products in the visible and infrared portions of the spectrum.’
The ams OSRAM PLPCOS 450D and PLPCOS 450E blue CoS laser diodes are available via any authorized distributor.
ams OSRAM also supplies blue laser diodes in a TO package, in versions with a 5W optical power output in TO90 format and 1.6W output in TO56 format.
Convergent Photonics is developing new laser modules which are ideal for high-power industrial and mid-power medical laser applications thanks to the introduction of a new chip-on-submount (CoS) package for 445nm blue laser diodes from ams OSRAM.
