Overview

High-Power 50W Blue Laser Module is design for such applications as plants, crops and weed laser processing, laser engraving and marking at high speed, food labeling and marking and many others.

Laser module is build with 12 high power blue semiconductor laser diodes. All of the laser diode are spatially combined to form one, unidirectional laser beam which can be focused into single spot. All of the optical components are precisely and accurately aligned at our laboratory with specialized equipment and tools.

Beam Spot Profile

Beam Profile of High Power Blue Laser Module

Beam spot of High-Power 50W Blue Galvo Laser Module is single mode in fast axis (vertical axis) and multimodal in slow axis (horizontal axis).

Measurement Conditions:

  • Laser beam focused with 500mm focusing lens;
  • Beam Profiler is placed in the focal plane;
  • Focal plane is defined as smallest beam size in the fast axis;
  • Laser operated in QCW, 100Hz 1ms pulse

High-Power 50W Galvo Laser Module is build with multiple laser diodes, every laser diode emits slightly different spectrum. As result emission spectrum of the laser module is relatively broad. For applications where narrower spectrum is required, laser diodes can be wavelength tested in prior to production so that when they are combined their spectrum matches.

Typical Power Drift and Warm Up Time

Power Drift of High Power Blue Laser Module

High-Power 50W Galvo Laser Module has passive cooling with four high performance fans. Typical warm up time of the laser module is below 10 minutes. After warm up time power drift is negligibly small (assuming the ambient temperature is stable). Measured with IS12L-9S-RSI-INT-D0 at 23 degrees Celsius ambient temperature (stabilized)

High-Power 50W Galvo Laser Module has three LPLDD-5A-24V-TP laser diode drivers inside. Each laser diode driver is powering four laser diodes which are connected in series.

Measurement conditions:

Signal: 1 kHz; 1% Duty Cycle; Square Wave; 5V Amplitude

Optical signal measured with Ultra-fast PIN Photodiode SFH 2701
