Laser emitting module, window cap, laser pointer, and light emitting module

A laser pointer comprising:

• a resonator including a solid-state laser medium, a non-linear optical element for converting a wavelength of light emitted from the solid-state laser medium, and a pair of resonance reflectors sandwiching the solid-state laser medium and the non-linear optical element for reciprocating the light therebetween;
• a laser diode for emitting light for exciting the solid-state laser medium;
• a window cap having a window section through which the light emitted from the resonator is outputted, for accommodating the resonator and the laser diode therein;
• an optical filter for selecting a wavelength of an output light emitted from the resonator;
• and
• a pair of convex and concave lenses for expanding and collimating light emitted from the window section into parallel rays of light.
