“…iSEE also provides sample context, including ice composition, crystallinity, and ice phase distribution [55]. We are currently developing a laser transmitter for the iSEE Raman spectrometer that is a frequency doubled Yb:YAG microchip laser that was previously developed under an ESTO funded IIP [56]. RAMS (Raman Mass Spectrometer) is a hybrid instrument that incorporates LDMS and micro Raman spectroscopy imaging (µRS) into a compact instrument package.…”

“…The RAMS laser is a diode pumped 1030 nm Yb:YAG microchip laser [56] similar to the iSEE laser with a SHG and FHG to achieve a visible and DUV output at 515 nm and 257.5 nm respectively, the fundamental 1030 nm laser operates at a PRF of 1-10 kHz with pulse energy of 95 µJ and ~800 ps pulse width. A Type II KTP crystal is used for SHG from 1030 nm to 515 nm, and a Type I BBO crystal is used for (FHG) generation from 515 nm to 257.5 nm.…”

At NASA Goddard Space Flight Center (GSFC), we have been developing spaceborne lidar instruments for space sciences. We have successfully flown several missions in the past based on mature diode pumped solid-state laser transmitters. In recent years we have been developing advanced laser technologies for applications such as laser spectroscopy, laser communications, and interferometry. In this paper, we will discuss recent experimental progress on these systems and instrument prototypes for ongoing development efforts.

“…Laser radiation with high beam quality, short pulse duration, high repetition rate, and high intensity can be obtained with the Master Oscillator Power Amplifier (MOPA) approach [11,12]. Both Yb 3+ -doped lasers [13] and Nd 3+ -doped lasers [14] can use the MOPA approach to achieve high energy sub-nanosecond pulses near 1 µm. Yb 3+ -doped lasers have wide gain bandwidth, high Stokes efficiency, and high saturation fluence and achieve pulse energy with hundreds of mJ.…”

We present a compact sub-nanosecond diode-end-pumped Nd:YVO 4 laser system running at 1 kHz. A maximum output energy of 65.4 mJ without significant stimulated Raman scattering (SRS) process was obtained with a pulse duration of 600 ps, corresponding to a pulse peak power of 109 MW. Laser pulses from this system had good beam quality, where M 2 < 1.6, and the excellent signal to noise ratio was more than 42 dB. By frequency doubling with an LBO crystal, 532 nm green light with an average power of 40.5 W and a power stability of 0.28% was achieved. The diode-end-pumped pump power limitation on a high peak power amplifier caused by the SRS process and thermal fracture in bulk Nd:YVO 4 crystal is also analyzed.

“…Therefore, Master Oscillator Power Amplifier (MOPA) configurations based upon low-loss PWAs offer a potential solution for direct amplification of lowpower single-frequency diode-lasers up to the power levels required for IPDA lidar. A PWA system has already been demonstrated in an airborne campaign, with ytterbium-doped Yttrium Aluminum Garnet (Yb:YAG) as the gain medium [4], proving that it is a viable source architecture for future observation systems.…”

We report on the fabrication and characterization of Er:YGG films suitable for waveguide amplifiers that could in principle be used in integrated path differential absorption lidar systems. Presented is our fabrication technique, comprising pulsedlaser-deposition growth of ~10 µm-thick crystalline films, their channeling via ultraprecision ductile dicing with a diamond-blade, producing optical quality facets and sidewalls, and amplifier performance. Net gain at 1572 nm and 1651 nm is obtained for the first time in Er-doped YGG waveguide amplifiers. Additionally, in a channel waveguide a maximum internal gain of 3.5 dB/cm at the 1533nm peak was realized. Recent crystal film quality improvements promise further performance enhancements needed for the intended application for high-peak power sources in the 1.6-µm spectral region targeting Earth observation systems for monitoring greenhouse gases.
