Del Mar Photonics collaborate with Quartus Engineering team to offer full service in opto-mechanical design and fabrication. Many opto-mechanical systems required to meet tight optical spacing, tip/tilt, and centration specs to achieve system boresight and beam/image quality. Active systems incorporate the focus, pointing, etc. adjustments at the resolution and accuracy required of the deployed system. Structural and thermal analyses allows to verify mechanical integrity and performance under aggressive conditions, including high g-loading, severe vibrations, extreme temperature variations typical of military aerospace platforms, including directed energy weapons, laser rangefinder/designator/illuminator, communications, and high resolution surveillance systems.

Del Mar Photonics offers pulsed Nd:YAG lasers with excellent beam quality, high energy/efficiency and possibility of efficient pulse rep rate changes with no significant degradation of the beam parameters.
Ring cavity design of the LQ529 oscillator ensures perfect balance of energy, beam quality and reliability.
Supplementing the basic model with a one­pass amplifier allows to provide up to 1500mJ output energy in the fundamental (model LQ929) while preserving all the advantages of the LQ529 model.
Applications include nonlinear optics, spectroscopy, velocimetry, material processing, mobile laser systems.
Model LQ929 is an ideal pump for second stage amplifier for terawatt Ti:Sa lasers

Hydrogen Thyratrons are used in such devices as radars with different power levels, high-power pulsed lasers and many others. Sophisticated design and high quality ceramic-metal envelope determines long lifetime and very accurate and reliable operation of thyratrons under wide range of environmental conditions.
Applications:
- radars
- pulsed lasers power supplies
- medical apparatus
- electrophysical instrumentation

Del Mar Photonics offer ceramic-metal thyratrons with hydrogen and deuterium filling. Most of the thyratrons have tetrode structure which permits to achieve a high stability of discharge development and an enhanced switching speed. Use of selective gas getters in combination with special vacuum production process ensures a long operating lifetime.
 

JAWS is a terawatt femtosecond chromium-doped forsterite (Cr4+:Mg2SiO4) laser system, based on an oscillator, regenerative amplifier and four stages of multi-pass amplifiers. The system can generate 80 fs pulses at 1240 nm wavelength, with pulse energies of 85 mJ giving a peak power range of 1-2 TW at 10 Hz and is assembled on a single 1.2×3.0 m optical table. Cr:forsterite is directly pumped at 1064 nm removing the need for more expensive green pump lasers. Fundamental, 2nd and 3rd harmonics of Cr:F laser are convenient for a number of applications in time-resolved spectroscopy, telecommunications, photochemistry, photobiology, plasma physics, VUV, x-ray generation, and material processing. Wavelength range is also well outside the visible and shows significantly less pulse broadening in atmosphere than 800 nm.

more details

The Pismo pulse picker system comprises of a control and power supply unit (CPSU) and a Pockels cell with a HV driver.

The CPSU realizes the following functions: synchronization to a pulse train, amplifier pump laser start (flash-lamp or diode pumped with acoustooptical or electrooptical Q-switch) synchronously to the picked pulses, oscilloscope synchronization, streak-camera synchronization and other
equipment that requires synching to a pulse train. The CPSU has 5 independent delay channels that are rigidly fixed to a fs pulse train (jitter <200 ps). One CPSU can manage up to 4 Pockels cells. The Pockels cell consists of a HV pulse driver and an EO crystal. The HV driver produces a bell-shaped HV pulse with duration of <10 ns at level 10 % from maximum (rise/fall time <4 ns). This pulse is then supplied to the DKDP electrooptical crystal. Typical Specifications
