4. The laser head of the LMX includes some temperature regulation loops These elements sharply increase their power consumption as the temperature of the base plate drift out of a range typically between 20 C and 30 C In order to minimize the consumed electrical power from the laser head the user should thus increase the flux of dissipated heat for example by selecting a heat sink with a minimized thermal conductivity and or applying a stronger air flow through it For example decreasing the base plate temperature of the LMX head from 45 C to 25 C can typically yield a 30 reduction of the total power consumption 24 LASERBOXX ADVANCED USE 3 2 2 Front panel description The front panel of the OEM controller appears as in figure 31 below Figure 31 Front panel of the OEM controller The front panel features the following elements E9 Low voltage inlet socket E5 CONTROL port see section 4 2 RS 232 communication port see section 4 3 E8 USB communication port see section 4 3 Note Oxxius can provide a dedicated power supply referenced SLIM OE P S Do not hesitate to contact your local representative and inquire about this accessory 3 2 2 1 POWER connector pin out diagram The schematic below shows the end face of the input POWER connector on the electronics controller and its pins connections Input voltage 0 VDC Ground Figure 33 POWER connector pin assignment Note The conne

The classification of a laser is based on the concept of accessible emission limits AEL that are defined for each laser class This is usually a maximum power in W or energy in J that can be emitted in a specified wavelength range and exposure time It is the responsibility of the manufacturer to provide the correct classification of a laser and to equip the laser with appropriate warning labels and safety measures as prescribed by the regulations The identification process is accomplished by affixing a label onto the product Along with text warnings these labels include information pertaining to the wavelength total output power and laser classification Safety Guidelines Everyone who uses a laser should be aware of the risks This awareness is not just a matter of time spent with lasers to the contrary long term dealing with invisible risks such as from infrared laser beams tends to reduce risk awareness rather than to sharpen it Please take time to read and understand this user manual and familiarize yourself with the operating and maintenance instructions that have been provided before using the product If there are any questions or sections that are not understood do not hesitate to contact the manufacturer Optical experiments should be carried out on an optical table with all laser beams travelling in the horizontal plane only and all beams should be stopped at the edges of the table Users should never put their eyes at t

51. voltage to 4 2 V ensures a proper operation of the laser module In order to check the actual input voltage while the laser is in operation the CONTROL port can be used The input voltage provided to the controller can be read between pins 9 and 15 of the CONTROL connector Input Voltage Figure 32 Checking the input voltage CONTROL port You can also query the input voltage as measured internal by the laser head using a dedicated software command see section 4 3 3 2 1 3 Thermal management Both the LMX laser head and its controller generate a certain amount of heat while they operate The total dissipated heat is typically maximum at the highest allowed operation temperature For this reason the base plates must ensure an effective heat dissipation This is best achieved using a heat sink Additionally employing conductive paste such as the Arctic Silver 5 thermal grease is recommended in order to improve the thermal conductivity between the LaserBoxx elements and their support Should the operating temperature go beyond the limits given in the table below there will be a warning raised status LED blinking red Furthermore the laser operation will stop and the controller will indicate an alarm status LED lit in solid red See also sections 8 1 1 for a detailed flow Standard operating range A H base plate temperature piede ae Warning raising temperature ranges 10 15 C or 45 50
52. y voltage is detected as insufficient Instabilities of the optical output power To check if the voltage suppiled to the laser unit is sufficient and stable use the query va see section 4 3 4 for details or measure it from the relevant pin of the CONTROL port see section 3 2 The wires supplying the current from the power supply to the laser controller will cause a voltage drop depending on their length and section The voltage measured at the inlet socket of the controller as indicated on the schematic below must be within its nominal operating range LaserBoxx Controller Power supply Measurement point Figure 8 1 Measurement of the supply voltage 8 1 3 Issues with back reflection An excessive light entering the laser module either from back reflections of its beam or from other light sources in the setup will lead to an unstable operation of the LMX In order to assert this cause of instability it is recommended to start the laser with its shutter or any other beam dump closed and note whether the laser starts normally under these conditions 51 8 1 4 Other issues Maintenance is limited to replacing the fuse on the AC power line of the Plug amp Play controller The replacement procedure is as follows 1 Unplug the power cable from the wall socket then from the LaserBoxx controller 2 Open the fuse hatch and replace the damaged fuse with a new one The fuse has to be a slow blow fuse rated for 1
