Abstract: Provided may include an electron beam generator, an image apparatus including the same, and an optical apparatus. The optical apparatus includes a first and second laser apparatuses providing a first and second laser beams on a substrate, and a first optical system provided between the first and second laser apparatuses and the substrate to focus the first and second laser beams. The first and second laser beams overlap with each other generating an interference beam, thereby decreasing a spot size of the interference beam to be smaller than a wavelength of each of the first and second laser beams at a focal point.

Abstract: Disclosed is a high power ultra-short pulsed laser device increasing pulse energy by using resonators. A pulsed laser device may comprise a first resonator making a pump beam resonate primarily and passing the pump beam which resonated through a first output mirror; and a second resonator comprising a first multiple reflection mirror and a second multiple reflection mirror. Also, the first multiple reflection mirror includes at least one first small area mirror, and the second multiple reflection mirror includes at least one second small area mirror, and the second resonator makes the laser beam delivered from the first resonator resonate by reflecting the laser beam repetitively. Therefore, the pulsed laser device may increase pulse energy without using a multi-stage amplifier so that a high power ultra-short pulsed laser beam can be generated.
