Picosecond synchronously pumped diamond Raman laser

Abstract

Abstract With diamond crystals as Raman media, picosecond synchronously pumped solid-state Raman laser is theoretically studied in detail for the first time. High efficient working point and effective pulse compression working point are investigated. For both 532nm and 1064nm pumping, high Raman conversion efficiency can be achieved for negative cavity length detuning (Δx) and diamond crystal length of 5mm. The higher efficiency can be obtained with longer Raman crystal, longer pumping pulse width and higher pumping power. For 532nm pumping, effective pulse width compression can be realized for Δx = 0 nearby and diamond crystal length of 10mm. Shorter pulse width and higher peak power of 1st Stokes laser can achieved with longer Raman crystal, shorter pumping pulse width and higher pumping power. The findings can contribute to the design and optimization of picosecond synchronously pumped diamond Raman lasers.
