“…This feature makes these Q-switched microchip lasers extremely suitable to uncomplicated, pump-scavenging amplification architectures [27], that can bring the overall system efficiency and pulse energy back up to levels of greater practical utility.…”

We evaluate the design of Q-switched microchip lasers to examine the limit of their scaling to shorter picosecond pulses. A numerical model based on the laser rate equations is developed and used to predict the output characteristics of prospective laser designs. Based on the modeled results, we employ a SESAM as a passive Q-switch and thin crystals of Nd:YVO 4 as a gain medium to experimentally demonstrate the production of pulses as short as 22 ps.

“…For laser radar measurements with the integrated GM APD array, a custom tunable microchip laser source was developed. The laser source is pumped by a passively Q-switched [7,8] Nd:YAG (neodymium-doped yttrium-aluminum-garnet) laser which is itself pumped with a 808-nm cw diode pump laser. The 1.064-μm pulse produced from the microchip laser is used to pump a periodically poled lithium niobate (PPLN) [9] crystal patterned with a linear array of gratings.…”

A 32x32 Sb-based Geiger-mode (GM) avalanche photodiode array, operating at 2 μm with three-dimensional imaging capability, is presented. The array is interfaced with a ROIC (readout integrated circuit) in which each pixel can detect a photon and record the arrival time. The hybridized unit for the 1000-element focal plane array, when operated at 77K with 1 V overbias range, shows an average dark count rate of 1.5 kHz. Three-dimensional range images of objects were acquired.

“…In the past 20 years, extensive efforts toward the development of nonlinear-optical crystals have been aimed at producing such a laser by means of frequency conversion of high-power solid-state lasers [10-12, 9, 13-17]. Most of the research on the UV radiation has been focused on pulse lasers [18][19][20][21][22][23][24][25][26]. Very little work about the continuous-wave (cw) UV radiation has been reported.…”

303.5 nm cw Pr:BYF–BBO laser emission under 447 nm all-solid-state Nd:GdVO₄–BiBO blue laser pumping

An all-solid-state blue laser-pumped Pr:BaY 2 F 5 (Pr:BYF) laser at 607 nm has been demonstrated. With an incident 447 nm pump power of 1.04 W, the maximum orange output power was 337 mW. Moreover, intracavity second-harmonic generation (SHG) has also been achieved with a maximum UV power of 76 mW by using a β-BaB 2 O 4 (BBO) nonlinear crystal. To the best of our knowledge, this is the first report on continuous-wave (cw) UV generation by an intracavity frequency doubling Pr:BYF laser.
