21. The noise output power  randomly switches among several output levels. 22. Generally, M 2 increases as a laser's output power  increases. 23. Until now, it is the standard method of measuring output power  for physiotherapy systems. 24. The circulating amplitude increases with increasing pump power, and so does the output power . 25. The output power  of a laser pointer is usually stated in milliwatts ( mW ). 26. Other approaches have encountered unexpected problems that greatly increased the difficulty of producing output power . 27. Its payload is composed of twenty-four 36MHz TWTA output power  of 120 Watts per channel. 28. Under such a condition, the amplifier will produce at or near its maximum output power . 29. Its TWTA with an output power  of 108 Watts. 30. This resulted in a shorter but wider engine for the same airflow and output power .
