4 new IBS coating machines

Double IBS capacity in 2015
LASEROPTIK enlarges from four to eight industrial IBS systems e.g. for ultrafast optics, complex filter designs or in the UV. With a custom built giant machine, LASEROPTIK also offers coatings on substrates up to 2 metres in length, made by IBS.

IBS coatings up to 2 m





LASEROPTIK now designs and produces dispersion-matched pairs of broadband chirped mirrors for even better GDD compen-sation.

 

 

 



Solid etalons

 

Solid Etalons
Uncoated Suprasil ® 311 plates,
wedge < 0.2 arcsec

Fabry-Perot etalons are extremely narrow line width filters with a series of sharp transmission peaks, separated by the free spectral range (FSR).

FSR depends on the optical thickness of the etalons only, whereas the finesse (F) is determined not only by the reflectivity of the coatings, but mainly on surface quality, parallelism, homogeneity of the substrate material and defect free coatings.

Solid etalons can be tuned by tilting and by temperature change. If a minimum resolvable resolution is needed, the reflectivity finesse FR can be calculated with



With the diagrams the reflectivity R of the layers can be determined.The final finesse of the etalon is limited in most cases by the flatness finesse FF (flatness of /20 gives FF = 20) for beam diameter 20 mm. With thinner beams FF can grow to > 200.

Pairs of etalons in series may be used to obtain ultra high resolution combined with a very long FSR. The resulting finesse of such a combination can be one oder of magnitude higher.

Besides lower costs solid etalons offer the following advantages over air spaced etalons for intra cavity use:
• higher transmission
• lower size harder coatings with
• higher damage thresholds.
