An inherently efficient direct eye-safe laser based on Er:Crystal technology
utilizing
intra-cavity energy conversion. The Er:Crystal laser is intra-cavity pumped by
a highly efficient ytterbium or neodymium crystal laser, which is in-turn, pumped
by conventional infrared diodes array bars. The laser is inherently compact and
low-cost allowing for significant scaling of the output energy and power with greatly
reduced number of required diode pump sources. This intra-cavity pump scheme of
appropriate Er:Crystals also provides for efficient generation of ultra-short Q-switched
pulse operation of such lasers.
