TOPTICA presents new OEM Platform for Blue Diode Lasers –the compact Solution for Interferometric Applications

TOPTICA Photonics AG introduces a new technology platform featuring its proprietary "Blue Mode” technology. This term stands for high power and ultra-narrow line width OEM diode lasers in the blue-violet wavelength regime.

To-date, researchers and engineers using interferometric or holographic applications in the blue-violet spectral range were bound to deal with bulky, power consuming ion lasers. Intense blue laser diodes have been available but fell short of the required coherence properties. On the other hand, grating-stabilized blue diode lasers provided a spectrally narrow emission line, but were limited in their output power to well below 20 mW. For the first time, TOPTICA’s new Blue Mode technology unites all of the well-known advantages of direct blue-violet diode lasers: high power, high coherence, and superior long-term mode stability. TOPTICA’s sophisticated engineering incorporates all of these features in a compact, rugged design.

The Blue Mode technology currently starts with 50 mW @ 405 nm, with a spectral line width of less than 10 MHz (coherence length > 10 m guaranteed). A power stability better than 0.6 % in 10 hours has been demonstrated. Combined with an excellent long-term coherence stability (no mode hops), this renders these lasers a perfect fit for demanding applications such as interferometry, holography or high resolution RAMAN spectroscopy.
