Abstract
An intra-cavity high order harmonic laser consists of a output coupler, total reflection mirror, and a laser medium disposed therebetween. The output coupler and the total reflection mirror form a resonator. At least two nonlinear crystals are disposed between the laser medium and the output coupler. One of the crystals acts as a frequency doubler, doubling the fundamental frequency of the laser and the other crystal acts as a frequency mixer or high order harmonic doubler in order to produce higher nth order harmonic (n.gtoreq.2). The invention overcomes the disadvantages associated with producing a high order harmonic laser beam in low peak power lasers such as CW lasers.
