The K808DA5RN-60.00W is a high-power fiber-coupled laser diode delivering 60W of Continuous Wave (CW) output power at a center wavelength of 808nm (±3nm). The ±3nm wavelength tolerance is notably tighter than the ±10nm specification on lower-power 808nm modules — a meaningful advantage for solid-state laser pumping applications where consistent pump wavelength overlap with the Nd:YAG or Nd:YVO₄ absorption peak at 808nm directly determines pumping efficiency and thermal stability of the gain medium. The K808DA5RN-60.00W stands out in the 808nm lineup for combining high power (60W) with a compact 105μm core fiber (0.22 NA) — the smallest core diameter in the 808nm range — while achieving a high slope efficiency of 7 W/A typical. This high brightness-per-watt output enables efficient coupling into tight pump input apertures in end-pumped solid-state laser rods and compact fiber laser pump combiner ports. Output is delivered via SMA905 termination through a 3mm loose tubing, 2-meter pigtail with 50mm minimum bending radius, enabling direct plug-in to standard SMA-ported laser systems. The 6-pin package includes LD drive pins (1 & 2) plus optional thermistor (Pins 3 & 4) and PD monitor (Pins 5 & 6) functions, giving OEM system designers the flexibility to enable closed-loop temperature and power control when needed without requiring a more complex dedicated module. The 30dB feedback isolation band (1020–1200nm) protects the diode against back-reflected Nd or Yb laser signal light in pumping applications.
