Blue Laser Light Monolithic focusing optics for single emitter diode lasers
Quote:
The Dortmund-based [LIMO Lissotschenko Mikrooptik GmbH ] company has developed micro-optics for 'true' blue, high-performance single emitter diode lasers; the technology focuses the beam with precision on an area measuring approx. 40 x 40 µm². Micro-optics technology is ideally suited for pumping solid-state crystals or for fiber coupling.
Quote:
The new trend is towards single emitter diode lasers (spectral width: 420 to 470 nanometres) which, due to higher outputs of up to 1-2 W , are becoming increasingly popular in lithographicy . . .

The new devices have already been successfully deployed for energy-efficient solid-state crystal pumping within the scope of the project 'Integrated Green Efficient Laser' (IGEL), which the German Federal Ministry of Education and Research (BMBF) has funded with EUR 3.5 million. The term 'green laser' may be misleading for some: The actual light source is a blue laser diode, the wavelength of which is converted upwards within the crystal to produce a green laser beam.

Micro optics for DPSS in a diode can. I like it.

40X40 um means there might be no astigmatism/aberration in the output.

Thanks for sharing!

Very cool!

So wait, they're turning the frequency down?....

I've only heard of the opposite... sounds interesting!
