April 8, 2009: Opto-mechanical design and fabrication
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.

April 6, 2009: Hydrogen Thyratrons
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.

March 25, 2009: JAWS multi-terawatt Cr:forsterite laser
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.

March 25, 2009: Pismo Pulse Picker
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.

Ti:Sapphire
laser helps Physical Optics Corporation in Phase I and Phase II
Army awards.
To address the U.S. Army need for new techniques for detecting concealed
explosives, Physical Optics Corporation (POC) proposes a new 100 m standoff
Terahertz Spectroscopic Radar (TSR) which uses terahertz (THz) molecular
spectroscopy to detect the unique THz absorption wavelength signature of an
explosive's outgassed material. This design exhibits the most decisive
identification pattern of explosives, whose molecular vibration modes lie in
the THz region. To detect these specific explosive identifiers, TSR's
innovative
design analyzes the retroreflected THz signals from targets rather than the
transmitted THz signals common to the conventional spectroscopy performed
inside a laboratory. The TSR design combines a wideband (1-20 THz) transmitter
and a
receiver spectrometer, built on a mobile station. Using a high-quality
submillimeter wave radar to send high rep-rate (~100 MHz) THz probing pulses,
POC system can identify not only the explosive but also the location of the
target with spatial resolution better than 0.03 mm since our radar pulsewidth
is faster than 100 femtosecond (fs). The average power of our source is
exceptionally high (~100 W) compared with any other THz sources. In Phase I
POC buill a preliminary TSR prototype, while Phase II will focus on a full
engineering prototype.
Ti:Sapphire laser for THz spectroscopic radar.
Latest results on using femtosecond lasers for THZ generation will be
presented by POC at SPIE DSS 2009.
