Measured and simulated output-power-vs-current characteristics when operating RWS and TS at equal current densities. The inset shows the schematic of the present tapered diode laser.
(a) Experimental and (b) simulated output-power-vs-RWS-current characteristics for different pulsed operation currents of the TS.
Calculated optical power at the beginning of the TS vs TS current at the saturation point [see Fig. 2(b)].
Color-coded lasing spectra for (a) constant pulsed TS current and varying cw RWS current and (b) constant cw RWS current and variable pulsed TS current.
Output power vs TS current for cw and pulsed mode operation ( pulse length, repetition rate).
