Q-Switched IR Laser (PDF, 0.18 MB)
The JDSU M110 lasers are mini Q-switched, air-conduction-cooled devices employing an Nd:YLF gain material, a laser pump source, and pulse-on-demand system control capabilities. The patented cavity design features a high-opticalpower density laser pump efficiently and compactly coupled to the laser cavity, Brewster-angled intracavity surfaces, proprietary mounting of optical elements, and minimal use of optical coatings. These design features ensure highly efficient operation and minimal feedback. As a result, diode power can be decreased, significantly lengthening the diode’s life.
The M110 lasers operate many times above lasing threshold, so a large number of longitudinal modes are present and significant averaging occurs while reducing spiking and improving pulse energy stability. The Nd:YLF gain medium is also advantageous in this respect, since it has a broader emission bandwidth than Nd:YAG, thereby supporting more longitudinal modes. The net result is excellent energy stability, typically <1.0% rms. The pulse-energy equalization feature allows user to specify the highest repetition rate at which the laser will operate, and it then keeps the pulse shape constant for lower repetition rates. First-pulse suppression eliminates unwanted large pulses at the beginning of a burst of pulses to insure no damage to laser, user optics, or material in process.
The M110 laser series also provides three operational modes: continuous wave (CW), internal trigger, and external trigger. Several pulse width versions are available.
