Abstract
The present invention relates to a green laser generation device which can be applied to a cellular phone, and more particularly to a green laser generation device which is ultra compact in size having volume of 1 cc or less, despite having a built-in thermo electric cooler, and has sufficient output power, despite having low power consumption, and a portable electronic machine having a laser projection display using the said device. The present invention provides a green laser generation device comprising an LD pump constituted by a photo diode; a fundamental generator generating infrared light laser according to the driving of the LD pump; a second harmonic generator generating green light using the generated infrared light laser; a polarization maintenance unit inserted between the fundamental generator and the second harmonic generator to maintain the polarization of the laser; and a temperature controller controlling an internal temperature of the green laser generation device.
