DIODE-PUMPED SOLID LASER COMPRISING A THERMAL LENS INSIDE THE RESONATOR |
| 摘要 |
The invention relates to a diode-pumped solid laser comprising an asymmetrical optical resonator which is provided with at least two resonator mirrors and comprises at least one thermal lens having an optical refractive power D and respectively two main planes and can be described by the following stability criteria: 0<G1-G2<1 WHERE G1 = 1 - L*/R1 - D.d2, G2 = 1 - L*/R2 - D.d1 and L* = d1 + d2 - D.d1.d2, d1, d2 representing the distances between the resonator mirrors and the main planes of the thermal lens, and R1, R2 representing the curvature radius of the resonator mirrors. The invention is characterised in that the variables d1, d2, R1 and R2 are selected in such a way that, for the following critical refractive powers DI, DII, DIll and DIV for which (I) holds good, the following relations are satisfied: DII-DI = DIV-DIII = 8 dptr. aeDIII-DII<= 2 dptr>. |
