Product description

Overview

FS-50W Blue Laser Source is a new design of a high-power multi-laser head. It uses new technology for astigmatism compensation of semiconductor laser beams. Thanks to our sophisticated optical solution it provides the possibility to focus output beams to a single spot of a small size, even with a focusing system with a long focal length. High focusing capability of the output beam makes the module especially suitable for use with galvo scanners.

Beam Spot Profile

Beam Profile of High Power Blue Laser Module

The beam spot of FS-50W Blue Laser Source is single mode in fast axis (horizontal axis) and multimode in slow axis (vertical axis).

Measurement Conditions:

  • Laser beam focused with 170mm focusing lens;
  • Beam Profiler placed in the beam waist plane;
  • Beam waist plane defined as the highest power density plane;
  • Laser operated in a quasi-CW mode with 100Hz frequency and 1ms pulse duration

High-Power 50W Blue Laser Module is built with multiple laser diodes, each of which emits slightly different spectrum. As a result, the emission spectrum of the laser module is relatively broad. For applications where narrower spectrum is required, laser diodes can be wavelength tested prior to production. This meticulous testing ensures that when the laser diodes are combined within the module, their individual spectra align to create a matched spectrum.

Typical Power Drift and Warm Up Time

Power Drift of High Power Blue Laser Module

Thermal processes in the laser head cause thermal drift of laser light power. Until the thermal equilibrium of the device is reached, power of the output light beam changes slightly. The FS-50W Laser Source requires up to 30 minutes of working to stabilize the level of the emitted light power. Power fall could reach 5% during the first half hour of working. After that the power stabilizes and next flows are caused by laser diode aging.

Typical Rise and Fall Time

The laser module is integrated with a driver that provides power supply required by lasers. The driver can work in continuous and pulse modes. In the continuous mode the light power depends on the voltage level fed into the analog modulating input. Modulation bandwidth of this input is limited to a frequency range of 0-500kHz; In the pulse mode the light can be modulated with voltage pulses fed into the digital modulating input. Laser light pulse duration depends on the modulating voltage pulse duration. Highest possible pulse repetition rate is determined by rise and fall time of the light pulses on the output of the laser module. For the FS-50W laser source, the typical value of the rise and fall time is less than 1.5μs and F_pmax equals 300kHz.
