41. In the realm of very high output powers , the KTP crystal becomes susceptible to optical damage. 42. Output power was typically 20 watts, exceptionally 35W.43. The higher engine output power requires liquid cooling with a separate radiator mounted on the propeller mast. 44. Power required to drive the pump is determined by dividing the output power by the pump efficiency. 45. So the output power depends linearly on the spontaneous emission rate and exponentially on the optical gain. 46. The TOI is always beyond operational power levels because the output power saturates before reaching this level. 47. A hybrid turbocharger can revert to compressor mode during commands for large increases in engine output power . 48. A summary on the progress made in the output power density of triboelectric nanogenerators within 12 months. 49. It is typically assumed here that mechanical transmission allows the powerplant to operate at peak output power . 50. Driving an amplifier into clipping may cause it to output power in excess of its power rating.
