Title:
MULTI-OUTPUT HARMONIC LASER AND METHODS EMPLOYING SAME
Document Type and Number:
WIPO Patent Application WO2005114801
Kind Code:
A8
Abstract:
A solid-state laser (10a) has a laser resonator (20a) with output ports (22a1, 22b1) at both ends to provide two separate laser micromachining beams (42a1, 42bl ). A set of wavelength converters (26al, 26b1) can be employed to convert the laser mino-machining beams to harmonic wavelength outputs, thus reducing the risk of damage to the wavelength converters and enabling higher total average harmonic c power to be generated from a single laser. The laser mino-machining beams can be different to perform different laser operations independently or can be adapted to have substantially identical parameters to permit simultaneous parallel high-quality laser operations on substantially identical workpieces (54), or the laser micro-machining beams can be combined to provide a single laser system output (42e). The two laser machining beams can be further split or multiplexed to suit particular applications.
