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-optical-
power 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 diodeâs 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.
