FS-30W High Power 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.

FS-30W Blue Laser Source 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.
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-30W 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-30W laser source, the typical value of the rise and fall time is less than 1.5μs and F_pmax equals 300kHz.
