Femtosecond Ti:Sapphire oscillators and amplifiers from Del Mar Photonics
Do you plan to build a femtosecond set up based on Ti:Sapphire laser?
We offer several oscillator and amplifier options:
Femtosecond Ti:Sapphire Oscillator
1. If you already have a CW pump laser or plan to buy specific model and need only Ti:Sapphire oscillator we can offer our stand alone Ti:Sapphire lasers Trestles models, that do not include pump laser and can be customized for any suitable CW pump.
Please indicate required pulse duration (standard models have 20 fs, 50 fs and 100 fs pulses) and tuning range. Let us know what kind of pump laser you have (make/model) so we can confirm what output parameters can be achieved.
2. If you do not have a pump laser and want to buy complete system we can
offer you one of the following:
One-box system
Trestles Finesse that include Trestles mini Ti:Sapphire oscillator and built
in DPSS pump laser
When choosing specific Trestles Finesse model please indicate required CW pump power (4W or 6W), Ti:Sapphire pulse duration and required tuning range (or tuning range, where you want to achieve maximum performance)
Tuning range can be customized at the factory by choosing one of standard or custom made optics set. Typical tuning curves for 4W CW pump laser for two standard optics sets are shown in the Trestles Finesse brochure. For example, with 4W CW pump laser and long-wave mirrors set tuning range can be extended up to 940nm. With 6W CW pump laser tuning range can be extended up to 980nm.
Femtosecond Ti:Sapphire Amplifier
1. We offer integrated oscillator/amplifier system
Teahupoo Rider.
Teahupoo Rider is a fully-integrated all-in-one-box system that includes
Trestles Finesse
oscillator or
Buccaneer SHG diode-pumped fiber oscillator, pulse stretcher, regenerative
amplifier pumped by multi
kHz Nd:YAG pump laser and pulse compressor. Teahupoo Rider has a factory
preinstalled repetition rate of 2, 5 or 10kHz and ideal for low cost femtosecond
micromachining systems, OPA pumping, ultrafast spectroscopy and variety of
applications in life sciences.
2. If you already have a Ti:Sapphire oscillator, we can offer you stand alone Ti:Sapphire amplifier. Two standard models are available: Wedge M multipass or Wedge R regenerative.

Each amplifier is customized to the customer's amplifier pump laser.
2. Custom Teahupoo
Rider systems with a pump laser of your choice are also available. Depending
on the required specifications we can recommend a pump laser and make required
adjustments for optimum performance.
The following specifications can be achieved:
Repetition rate: single pulses, 10 Hz up to 10kHz
Pulse duration: 100fs, 50fs, 30fs, <30fs
Pulse energy: from 100 mJ per pulse to few mJ per
pulse
Tunability: both fixed wavelength and tunable options are available - please
indicate required tuning range.
Femtosecond Multipass Titanium : Sapphire Amplifier
System
< 50 fs pulse duration available
MPA50 Ti:sapphire amplifier system is based on the two-mirror confocal multipass Ti:sapphire amplifier designed for effective femtosecond pulse amplification in different active media1. The system includes:
1 See Ultrafast Phenomena VI (Springer: Berlin, Heidelberg) 1988, pp. 22-23
- Pulse stretcher
- Pulse picker and synchronization electronics
- Two-mirror confocal multipass Ti:sapphire amplifier
- Pulse compressor
- Frequency doubled Nd:YAG pump laser
Femtosecond seed pulses received from femtosecond Ti:sapphire laser are temporally stretched in the pulse stretcher to avoid effects of peak power damage in the amplifier.
Electrooptical pulse picker is used to decrease seed pulse repetition rate to the pulse repetition rate of a pump laser.
Selected seed pulses are injected into the two - mirror confocal multipass Ti:sapphire amplifier. Our unique amplifier configuration contains two confocally placed concave mirrors of different radii of curvature with central holes. This telescopic configuration provides eight passes of the light beam through the common focus where Ti:sapphire crystal is placed. Several amplifier modifications were designed for different pump pulse energies.
Amplified pulses are temporally compressed to about 50 - 100 fs by one-grating pulse compressor.
Second harmonic generator, white light continuum generator and optical parametric amplifier can be used for wavelength conversion and wavelength tuning.
Specifications:
- Output pulse duration: < 50 fs for TISSA50 seed pulses
< 100 fs for TISSA100 seed pulses- Operation wavelength: 800 ± 20 nm
- Pulse repetition rate: 10 - 50 Hz1, 1 - 4 kHz2
- Output pulse energy: 0.5 - 1.0 mJ at 10 - 50 Hz, 0.1 - 0.4 mJ at 1 - 4 kHz
- Single-shot autocorrelator is available optionally
1 Lotis LS series of frequency doubled Nd:YAG pump laser is recommended
2 Solar LF2210 frequency doubled Nd:YAG laser is recommendedDownload a brochure about MPA50 (pdf file 117kB, requires Acrobat Reader)
