Abstract:
1. A femtosecond laser apparatus using a laser diode optical pumping module, the femtosecond laser apparatus comprising: a laser diode for pumping a light source; a half-wave plate for adjusting polarizing directions of pumping light sources arranged in sequence; a collimating lens and a focusing lens for effectively applying an output beam of the laser diode to a laser crystal and improving mode coupling; the laser crystal for focusing the pumping light sources; and dichroic mirrors disposed in front of and behind the laser crystal to reflect a laser beam and transmit the pumping light sources therethrough, wherein the half-wave plate, the collimating lens, the focusing lens, and the dichroic mirrors are integrated as one piece in the form of an optical pumping module through mechanical engagement, such that the optical pumping module is installed in a way to be separated from a laser platform.
