TheLightHUB®ULTRACompactLaserCombinercanbeequippedwithuptosevenDPSSordiode
lasersofdifferentwavelengthsinacompactandruggeddesign.Wavelengthsbetween375nm
and830nmandopticaloutputpowersupto300mWper
laserlinearepossible.TheCompactLaserCombinerscan
beequippedwithseveraltypesoffibresorusedinfree‐

2.7Thermal management and environmental conditions

Storagetemperature:‐20°‐85°C
Maximumrelativehumidity(noncondensing):<80%;upto30°C
Operatingaltitude(abovesealevel):under3000m
Storagealtitude(abovesealevel):upto13000m

Thespecifiedandrecommendedoperatingtemperaturerangeis15…35°C.Forthe
LightHUB®ULTRAlasersystemtheheatwillbedissipatedthroughitsbaseplate.
Therefore,itisessentialtoprovideenoughheatsinkatthemountingarea.
Thetotalheatdissipationunderworstcaseconditionisdependingonthenumberandtypeof
laserheadsinsidetheLightHUB®ULTRA.
ForaDPSSlaser10…15WandforaDiodelaser5…10Wofheatdissipationmustbecalculated.
Additionally,thetemperaturestabilizationofthesystemneedsupto150Wdependingonthe
environmentalcondition.
ForLightHUB®ULTRAsystems,themaximumnumberofDPSSlasersis4.Combinedwiththree
diodelasers,totally7lasersareinstalledforcalculatingtheworst‐caseheatdissipation.
Theworst‐caseheatdissipationwillbe:4x15W+30W+150W=240W
Werecommendusingaheatsinkwithathermalresistanceof0.05…0.06K/Woraheatsink
withathermalresistanceof0.25…0.3K/Wwithforcedaircooling.

WhenusingtheOmicronheatsinkoption,nofurthercalculationfortherequiredthermal
resistanceisneeded.
