Normal operation. Relative to specified output power Low Power Mode 30W - 300W Needs separate control mode activated Warm Up Time Short Term Power Stability (1Hz 1MHz) Long Term Power Stability (1 Sec 10 Hours) Fiber Laser Design Lifetime <5mins ( 1kW) <10mins (>1kW) <1.0% RMS ( 1kW) <2.0% RMS (>1kW) ±2.0% peak >40,000 Hours To reach specified power stability from cold After warm up time, under constant coolant conditions. At specified output power After warm up time, under constant coolant conditions. At specified output power MTBF, Mean Time Before Failure. Assuming 25 C coolant temp Laser Life Expectancy SPI s fiber lasers are designed using active and passive components including active and passive fibers. The optical characteristics of the passive components do not age appreciably over time or with use, nor do the characteristics of Page 2 of 9

3 the active fibers. The life expectancy of the fiber laser is therefore set by its other active components, and primarily by the pump diodes. The design lifetime for the pump diodes (an ensemble of fiber coupled laser diodes) is typically 100,000 hours MTBF. This MTBF is not until catastrophic failure, but to the time at which the current required to maintain output power exceeds a design limit. The quoted MTBF is for the ensemble of all individual laser diodes. For individual laser diodes, the MTBF is considerably longer, of the order of 1,000,000 hours, but it is the ensemble MTBF that is important when considering the product lifetime. Other active components within the QUBE fiber laser have shorter predicted MTBF s but these items are considered replaceable service items. 1.3 Beam Delivery Fiber Specification Output Fiber 20µm 50µm Beam Quality, BPP, (mm.mrad) Beam Divergence (mrad) 86% power enclosed Beam Divergence (mrad) 99.5% power enclosed 300W 1kW Output Fiber Length Option 1.5kW Output Fiber Length Option M (0.38) 100µm enhanced 100µm 300µm 2.1± ± ±0.6 13±4 82±12 170±30 130±25 180±30 175±40 <280mrad <240mrad <280mrad 300 <280mrad 5m, 10m 15m 5m & 10m 1.4 Alignment Laser 5m, 10m, 15m & 20m 5m, 10m, 15m & 20m PIPA-Q Output Connector As defined ISO Full angle at specified power Full angle at specified power Conduit may have occasional blemishes of purely cosmetic nature.
