Abstract
Solid state lasers are disclosed herein. An example laser disclosed herein includes a monolithic body having a first end and a second end. The monolithic body includes a first reflector disposed on the first end, a second reflector disposed on the second end, and a solid state gain medium and a Q-switch disposed between the first reflector and the second reflector. The example laser also includes a pump source to cause a population inversion in the solid state gain medium to cause the monolithic body to output a laser pulse. Various applications of the solid state laser are also disclosed herein.

1-28. (canceled)
A system for optically analyzing a sample, the system comprising:
- a pulsable laser configured to output a beam of light;
- a window disposed between the laser and the sample;
- at least one micro lens array configured to direct and focus the beam of light through the window onto the sample;
- and
- a detector configured to detect light that interacts with the sample, wherein the light that interacts with the sample is directed onto the detector by the second optical member and a third optical member.
A system for optically analyzing a sample, the laser, comprising:
- a pulsable laser configured to output a beam of light;
- a window disposed between the laser and the sample;
- a first optical member and a second optical member configured to collimate the beam of light output by the laser and direct the beam of light through the window onto the sample;
- and
- a detector configured to detect light that interacts with the sample, wherein the light that interacts with the sample is directed onto the detector by the first optical member and the second optical member.
A downhole production logging tool for analyzing a formation fluid, the tool comprising:
- a tool housing comprising a window;
- and
- an optical module comprising:
- a light source configured to output light;
- at least one optical member configured to direct the light through the window into the formation fluid outside of the tool housing;
- and
- a detector configured to detect light that interacts with the formation fluid and passes back through the window.
