Raman lasers intracavity resonator comprising a pump (11) and a RAMAN (12) resonator ELIMINATE ALIGNMENT PROBLEMS ASSOCIATED WITH LASERS intracavity OF faceting. PUMP resonators comprise a laser rod and a source of pump (14). In one embodiment, a first retroreflector (16) is disposed at an end of the resonator PUMP AND an output mirror is disposed at an end opposite THIS. A SWITCH Q, A dichroic mirror, and a prism (18) are disposed between the laser rod and mirror resonator out.The PUMP PUMP radiates energy to a first WAVELENGTH 1.06 (MU) M) between the first U retroreflective the output mirror. THE LASER RAMAN (12) comprises a gas cell RAMAN having a first (22) and a second lens (23) provided on ENDS THE OPPOSITE OF THIS to focus the laser energy within the cell RAMAN, and a second retroreflector (25 ) forming an end of the resonator RAMAN. The output mirror forms one end OPPOSITE CELL, AND dichroic mirror and prism are disposed between the second retroreflector and the first lens. RAMAN RESONATOR radiates energy THE RAMAN LASERS TO A second wavelength (1.54 (MU) M) between the second retroreflector and the output mirror. A second embodiment ELIMINATES THE SECOND AND retroreflective dichroic mirror and move QA switch position somewhere between the retroreflector and the laser rod. THESE ARE EXTREMELY INSENSITIVE TO LASERS Misalignment AND HAVE SAFE OUTPUT POWER FOR THE EYES AND ACCEPTABLE beam divergence. Lasers present a mechanism of production can be tolerated MECHANICALLY SO IS NECESSARY OPTICAL TRACKING NO.
