Application No. 08/312,780
Berger discloses a temperature stable solid-state laser
package. As shown in Figure 1, the laser package includes (1)
a laser crystal (i.e., solid-state laser active material 25,
typically in the form of a cylindrical rod), (2) a pumping
system (i.e., laser diode 31), and (3) a resonant cavity
(i.e., groove 21). Berger does not teach a Nd:YAlO laser

crystal or the pumping system including a presetting means for
setting in advance a value of output power of laser light and
a power supply for providing a pumping light source with a
suitable input power based on the output power value set by
the presetting means.
Ammann discloses a laser apparatus for producing a
coherent light output at visible portions of the spectrum. As
shown in Figure 1, the laser apparatus 10 includes a lasing
medium such as Nd:YAlO in a cavity defined by laser mirrors

12 and 13. Medium 11 is continuously pumped by a light source
(not shown) which may consist of krypton-arc lamps. Ammann
does not teach a pumping system having a presetting means for
