Electrical and Optical Characteristics / Typical Laser Specifications at 25° C *
Notes: * taken at internal temperature sensor, Depding on the laser wavelength an AR <0.7% (+10nm around peak wavelength) coated fiber facet or end cap on fiber module side is required. Avoid direct feedback from materials like mirrors, optics, processed material etc. back into laser module via the fiber cable by more than 10%.
(1) Power is measured ex fiber according to given fiber specifications including measures and tolerances of fiber and ferrules for uncoated fiber facets (exception see *). Minimum repeatable power with internal temperaure and current accuracy of +-0% is <=+-3% of maximum power. Please add tolerance of your temperature and current control.
(2) Do not exceed maximum forward current for rated power as given above by more than 5% otherwise the laser diode may be damaged
(3) Rule of thumb: Power ex fiber decreases by app. 5% (<1100nm), 7% (>1400nm) and 12% (>1900nm) every 10 °C temperature increase at internal temperature sensor. Lifetime decreases by about factor of two every 10 °C. Required flatness of customer heat sink 0.05mm over entire bottom surface to achieve necessary contact to the heat sink.
(4) Red and green minimum pilot power is set at factory by customer request. Standard is 3 mW.
(5) Adjust trimpot R6 to set maximum intensity with pin 10 control left open or set to 0.5V
(6) Adjust trimpot R4 to set intensity off with pin 10 control set to 5V
(7) Calculation of the thermal load and necessary thermal resistance of a heat sink to maintain internal diode temperature of 25°C :
Thermal load = Output power * (1/conversion efficiency - 1)
Heat sink thermal resistance = (25 °C - ambient temperaure) / thermal load
General Parameters / Accessories
* taken at internal temperature sensor ** we recommend to operate the laser above dew point. Below dew point water condensation on the exit window may damage the window when laser is switched on. If the module was stored below dew point before operation dry the window by pre-heating the module to 25°C

(4) Sensor signal range from (0.5-4)V and signal voltage depends linearly on humidity. 1.1V means app. 9% rel. Humidity and 4V means 100% rel. humidity.Voltage must be kept below1.1V for safe operation. Humidity (%RH) calculates from signal voltage by (signal voltage-0.82V)/ (0.032V/%RH). (5) You must use colourless , free of oil and greese DI water of tap water (>20 kOhmxcm , ph between 6-8, hardness <10dH or <200ppm CaCO3, particle diameter <200µm) Calculation example of thermal load and necessary water flow to maintain temperature difference of 10K between water and internal temperature sensor. Required water temperature and flow depends on maximum thermal load and maximum internal temperature.Thermal load is calculated as follows: Thermal load = Output power * (1/conversion efficiency - 1), Thermal resistance = temperaure difference of water to internal sensor / thermal load Water flow = Thermal resistance x water flux / Thermal resistance Example: Output power: 440 W at 9xxnm, Conversion efficiency: 0.45, Thermal load = 440 W * (1/0.45 - 1) ~ 540 W and water flow = 0.12 / (10 K/ 340W) = 6.5l/min
Fiber Connector
(1) Lumics laser diode fiber coupling technology ensures specified loss into the fiber cladding depending on the fiber core centricity,ferrule diameter and distance of the fiber end facet to the reference plane compliant with the shown technical drawing of the fiber connector (2) Free standing fibers suffer from higher risk of fiber damage to the fiber tip due to mechanical stress by handling and the fiber end facet can not be polished as simple as for not free standing fibers
