ABSTRACT:
The invention is directed to a frequency-doubling solid state laser having pump light sources at opposite ends thereof. A folding and out-coupling mirror is antireflection coated on both sides with respect to the wavelength of the light generated by the pump light sources. The pump light sources include a total of four laser diodes with each laser diode generating 3 Watts of light power. An output power at 532 nm is obtained using a Nd:YAG laser rod and a frequency-doubling crystal made of potassium titanyl phosphate. The folding angle defined by the folding and out-coupling mirror is in the range of 10.degree. to 60.degree. and is typically 50.degree..
