Abstract

The realization of solid-state Raman longitudinally diode pumped lasers, generating first and second Stokes components has been researched. The crystals of Gd ₃ Ga ₅ O ₁₂ :Nd ³⁺ , Y ₃ Al ₅ O ₁₂ :Nd ³⁺ and KGd(WO ₄ ) ₂ :Nd ³⁺ have been applied as an active elements. Giant pulse mode was obtained with the use of the passive Q-switch shutters based on Y ₃ Al ₅ O ₁₂ :V ³⁺ and Y ₃ Al ₅ O ₁₂ :Cr ⁴⁺ crystals. The first and second Stokes component conversion was performed using intracavity Raman conversion scheme with crystals KGd(WO ₄ ) ₂ and KY(WO ₄ ) ₂ Raman conversion elements. The possibility of an effective solid-state Raman conversion laser with end diode pumping emitting at the wavelength of 1.3152 microns has been demonstrated.
