1. General Information
1.1. Introduction
This manual contains information on the installation and operation of the TWL-
P-HS High Speed Tunable Wavelength Laser demonstration purposes.
1.2. Product Overview
The TWL-P-HS is a high speed, innovative, all-in-one tunable and
programmable laser source with high spectral purity. Based on laser crystal
technology, the TWL-P-HS can operate in three distinct modes: CW mode,
continuous scan mode, and programmable scan mode over the entire C-band
range. It also features variable scan speed up to 4000 nm/s. Its lightweight and
compact design allow it to be easily utilized both in laboratory and field
engineering applications. A built-in 7” touchscreen with intuitive graphical
interface gives the user full control over the operation of the device. In addition,
the TWL-P-HS can be controlled via remote software through USB or Wi-Fi. Its
polarization output and high wavelength and power stability make it a perfect
solution for a seed laser for optical modulation and other test and measurement
applications.
1.3. User Safety
1. The TWL-P-HS unit emits high intensity invisible light from the optical output
receptacle. Avoid direct exposure to skin and eyes.
2. The user should never open the equipment case; any attempt will void the
warranty and may result in electric shock and EMS attack to equipment in the
vicinity. If requesting to open up the unit for demonstration purposes, please
contact Optilab prior to doing so.
3. The user should avoid using any solvent or vaporizing chemical to clean the
equipment panel or case. It may result in damage to the surface and internal
circuits.

2. Operation
2.1. Introduction
This chapter describes how to operate the TWL-P-HS, and discusses the
location and function of the controls and connectors.
2.2. Initial Inspection
Your TWL-P-HS was carefully inspected before it left the manufacturer. It should
be in proper working order upon receipt. You should, however, inspect the unit
for any damage that may have occurred in transit. If the shipping container or
the packing material is damaged, keep it until the contents of the shipment have
been checked to be free of mechanical and electrical damages. Notify Optilab,
LLC promptly if any notable damage is found.
The TWL-P-HS shipment should include the following:
- TWL-P-HS device
- Power Supply

2.4. Operation Instructions
1.1.1 Start-up Procedure
1. Ensure the back surface of the TWL-P-HS has proper ventilation or heat-
sinking.
2. Connect the TWL-P-HS Output (2) to your system or test setup via a
patchcord or optical fiber before powering on the unit. The Output (2)
connector is FC/APC.
3. Depress and hold the power switch on the top left corner of the device until
the LCD screen powers on.
4. The Main page should now be displayed. The user can select between two
modes of operation: Continuous Wave (CW) mode or Sweep mode.
1.1.2 Continuous Wave (CW) Mode
1. To enable continuous wave mode, select the CW mode icon on the Main
page.
2. The continuous wave mode page is displayed as shown below.
3. Set the LD current (1) and Channel Number (2) to achieve desired power
and ITU grid wavelength.

4. The wavelength can be further adjusted using Fine Tuning (3).
FEATURE
FUNCTION
LD CURRENT
Sets the desired LD current from 0 to 250 mA. This will
control optical output power.
CHANNEL NUMBER
Sets the desired ITU channel number from 0 to 99. This
will set the output wavelength to the corresponding ITU
grid channel. Refer to table 1 at the end of this section.
FINE TUNING
Fine tunes the output wavelength.
BACK BUTTON
This button will lead you back to the Main page.
OPTICAL POWER DISPLAY
Output optical power display in dBm.
WAVELENGTH DISPLAY
Output wavelength display in nm.
1.1.3 Sweep Mode
1. To enable sweep mode, select the sweep mode icon in the Main page.
2. The sweep mode page is displayed as shown below.
3. Set the Start Channel (1) and Stop Channel (2) to set the desired sweep
range. The actual start and stop wavelength are displayed along with the
channel number.
4. Set the Sweep Time (3). This will determine the period of time it takes to
sweep from start channel to stop channel.
5. Set the LD Current (4). This will determine the optical output power.
