    Abstract: A modulated saturable absorber controlled laser. The laser includes an active medium (12); a saturable absorber material (18) operationally coupled to the medium to serve as a passive Q switch; and an energy source (20) disposed external to the medium for apply energy to the absorber. In particular embodiments, the energy source is a diode laser and focusing optics are included between the diode laser and the absorber. Modulation of the gain at the photon round trip time in the laser resonator causes a mode-locked laser output. A dichroic beamsplitter (24) is included in this embodiment for directing energy to the absorber. In an alternative embodiment, the diode laser is a quasi-monolithic diode laser assembly ring (27).

The laser (10) also includes a pump source (20) for pumping the gain particles (26) and a resonator (14) for amplifying and outputting laser light generated by the gain medium (12).

    Abstract: 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 (64), which is in-turn, pumped by conventional infrared diodes array bars (52, 54). 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.

    Abstract: A synthesizer includes a first resonator mirror, a second resonator mirror, and a gain medium disposed within a laser resonator cavity defined by the first resonator mirror and the second resonator mirror. The synthesizer includes a saturable absorber operationally coupled to the gain medium and having active control such that the saturable absorber is configured to generate a waveform via an injection locking signal to create a mode locking effect, the waveform having a frequency comb defined by dimensions of the gain medium. The synthesizer also includes a crystal electro-optical modulator disposed within the laser resonator cavity. The waveform passes through the modulator to impinge on a photodiode to output an emission RF waveform. Changing the voltage applied to the modulator changes the index of refraction of the modulator, altering an optical path length of the laser resonator cavity to adjust a frequency of the emission RF waveform.
