nach der Bestellung gedruckt Neuware - Printed after ordering - This work presents a fully semiconductor-based laser source that meets the requirements of coherent optical communication links in space and further allows to benefit from the numerous advantages of semiconductor lasers. A hybrid master oscillator power amplifier(MOPA) concept enables narrow-linewidth high-power operation.The experimental part of this thesis describes how the linewidth of the laser sources is characterized with a beat note measurement technique. A novel heterodyne linewidth measurement setup with a weak frequency lock of the two lasers features a virtually unlimited resolution. The analysis of the beat note signal is carried out by evaluating radio frequency beat note spectra as well as frequency noise spectra.Further, the characteristics of DFB and DBR lasers optimized for narrow linewidth operation are compared in terms of spectral stability, linewidth, and performance in a master oscillator power amplifier system. DBR lasers with an overall length of 4mm anda front facet reflectivity of 30% feature an intrinsic linewidth of 2 kHz at 180mW and a FWHM linewidth as small as 180 kHz up to an output power of 180mW. An intrinsic linewidth of 2 kHz is, to our knowledge, the smallest linewidth that has been reported in the literature so far.The concept of a hybrid integrated MOPA has been developed and the assembly procedure and the characteristics of the micro-integrated MOPA system are presented.The MOPA is realized on a footprint of 10 × 5mm2. The MOPA system features an output power of more than 1W, a FWHM linewidth of 100 kHz and an intrinsic linewidthof 3.6 kHz. To our knowledge, this is the first micro-integrated MOPA concept that simultaneously features narrow linewidth and addresses the requirements of spaceborne laser sources like mechanical stability, compactness, and efficiency.…

Information regarding the right of withdrawal
Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.
The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.
To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.
You shall send back the goods or hand them over to AHA-BUCH GmbH, Einbeck, Germany, without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.
Exceptions to the right of withdrawal
The right of withdrawal does not apply to:
- The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
- The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.
