Based on COHERENT's narrow band laser design, 30MW power output, narrow line width 488nm wavelength. Contains power control unit and laser two parts. The laser part is directly installed in the cylinder barrel of the original argon ion laser and communicates with the power control unit through the control cable. Newly designed power control unit with built-in microprocessor. The control interface and power interface are exactly the same as the original OEM power supply, so it can be used as a direct replacement.
