Many applications, including photo-poration of trapped cells, optical tweezing or chemical analysis, would benefit from a versatile, user-friendly laser, which could be able to be controllably switched between its continuous-wave (cw and cw mode-locked (ML)) regimes on short time scales, and also have its pulse parameters varied arbitrarily. We present the use of an optically-pumped saturable absorber (SA) inside Nd:YVO4 and Cr:LiSAF lasers as a viable method to remotely control the laser mode of operation.
